<P> During "Hold Your Piece", Alex hands Hanna the task of wearing a discriminatory Oriental - themed dress during her meeting with her oriental bosses . However, Caleb tries to invade the board and a dangerous gas is released from it, poisoning his eyes . With this, Hanna's reunion is interrupted right in the beginning when she is warned about what happened to him . Ultimately, Alex calls Hanna a loser and doesn't hand her piece of the puzzle . In the meantime, Aria and Emily team up to track down Sydney's whereabouts in hopes of finding Jenna . After searching her name online, they discover that Driscoll graduated from Berkeley College, with a double major in Economics and French . Sydney currently resides in a loft at Fishtown, Philadelphia, whilst working as a bank teller at a private department that services extremely wealthy clients . The girls also learn that Sydney checked into a charity gala for the Manhattan Children's Hospital, the same ball where Katherine made an appearance wearing Hanna's dress . Following this enlightenment, Emily googles the event and comes across a picture of Daly posing on a red carpet whilst Driscoll sneakily uses a phone to photograph her dress . The girls deduce that Sydney's loyalty to Marshall places her as the strongest contender serving as Spencer's shooter . They conclude Driscoll most likely made adjustments for Marshall to be clothed in a duplicate of Hanna's dress so Jenna could omit the truth from the authorities . Aria promptly suggests for her and Emily to head over to Sydney's address to gather more insight into the situation . Following a quick lesson from Caleb on spying techniques, Aria instructed Emily to approach Driscoll and clone her phone . During a conversation with Emily at an outdoor diner, Sydney explains that she tried to distance herself from Marshall over the years . Driscoll further adds that she did the coffee delivery unbeknownst that Noel and Jenna were intending to kill the girls . Their interaction is cut short once Sydney informs Emily that she has conference calls all afternoon . However, this information is quickly proven to be false . Through access to Driscoll's phone, the girls discover that Sydney had an appointment at the Vogel Vision Institute and eavesdrop the meeting . Turns out Driscoll was paying for an operation to give Jenna her sight back and she uttered the initials "A.D." as the donor for the cost . After Sydney exits the clinic, Aria and Emily aggressively confront her . Driscoll still claimed to not knowing where Marshall was, so Aria slipped a tracker in her bag to maintain her under their radar </P> <P> In "Power Play", Spencer arrives at her barn only to stumble upon her father's belongings . Amongst Peter's luggage, she finds his passport and discovers that he arrived in Philadelphia at the same time as Veronica . Peter suddenly emerges and Spencer engages in a heated argument with her dad, questioning him as to why he chose to avoid his own daughter . Peter divulges that he was searching for Mary's whereabouts and trying to assure she wouldn't return to Rosewood to cause more damage to their family . He further explains that he wanted to find a way to redeem himself after the emotional rollercoaster he put his daughter and wife through . When Spencer asks him if he was able to successfully track down Drake, Peter replies that he's working with a private investigator in order to do so . Spencer rebukes her father for attempting to chase Mary away, and storms out . The following day, Hanna is hanging out at Spencer's house when she spots the P.I.'s business card from Peter's briefcase . She convinces Spencer to infiltrate the investigation in order to locate Drake, and theorizes that Mary might be able to help point them in the direction of "A.D.". Afterwards, Hanna picks up the phone and calls the P.I., pretending to be someone from Peter's office . After getting help from the P.I., Hanna and Spencer knock on several doors until they approach one house and much to their surprise, Pastor Ted Wilson (Hanna's former step - dad) opens the door . The girls show Ted a picture of Drake and ask him if he has seen her, to which Wilson informs them that he hasn't . Hanna offers to grab coffee with Ted at the Radley later to catch up, and she also asks him to call her if he happens to spot Mary . As the Liars turn away to leave, Drake shows up in the doorway . Ted turns to Drake and questions her on what she's truly doing there . Later, he reaches out to Hanna to talk and they meet up at Lucas' loft, where Wilson reveals to have lied about Mary's visit . Ted further confesses that Drake is an ex-girlfriend of his back when he was a college student and that she met up with him to inform they had a child together . Things get even more intricate when Wilson discloses to Hanna that said offspring was Charlotte and that he knew his daughter prior to her sex change . It turns out that Ted used to run a summer camp for troubled boys, and Charles was a camper there . Wilson is disheartened when describing that he interacted with a "soft - spoken, sweet" boy without awareness they were related . Ted then showcases Hanna a picture of himself back when he worked at the camp, chaperoning Charles and Lucas Gottesman, whom he described as his son's "only friend". This shocking revelation leaves Hanna stunned . Later, when Spencer arrives home, she is reprehended by her father, who is mad that she spent the entire day looking for Drake . Peter claims that Mary's behavior in the past suggests she's unhinged . When Spencer demands her father to expose whatever knowledge he has on Mary, Peter finally gives in and discloses that the last time he saw Drake was after Spencer came back from rehab . Peter was in the kitchen drinking a glass of wine when he spotted whom he presumed to be Jessica quietly descending the staircase and making her way to the front door . Just before she exited, Peter turned the lights on and confronted her, until the woman explained to her former lover that she needed to see their daughter, prompting him to realize that it was actually Mary . Peter further clarifies that Mary pursued retribution after Jessica told her that Charles committed suicide in order to withhold information about his transition into a woman . After Peter refused to aid Drake on her vendetta, Mary used Peter's heart medication pills to poison her sister and proceeded to bury her on the Hastings' backyard . At last, Spencer comprehends her father's concern, seeing as Drake wanted to blame Peter for Jessica's murder . That being said, Spencer is disappointed to learn that Peter knew about Charlotte's connection to their family prior to exposing herself as "A". He then assures his daughter that despite her hard feelings, he'll always guard her from harm . Meanwhile, Emily reveals that Driscoll played them and left the device on a greyhound to Philadelphia . Aria receives a FaceTime call from a blocked number on her iPad . Once she answers, we see "A.D." in a black hoodie on the other end . The mysterious entity divulges to Aria they own a stolen file from Jessica DiLaurentis' burnt lair at Carol Ward's storm cellar containing information that could send Ezra to jail . Aria immediately disconnects the call, marches over to the board game, and hurls her player piece across the room . Later in the episode, Aria and Alison are following the game's directions for Ali's turn . Abruptly, the game phone starts making a quacking sound in Ali's purse, which confuses the two girls momentarily until Aria spots a nearby store called the Darling Duck . There, Alison discovers that Emily's donated eggs were fertilized and implanted inside her uterus . Suddenly, Aria gets another FaceTime request on her phone, so she urges Ali to go inside, assuring her that she'll meet her in a minute . When Aria glances down at her phone, she sees a message from "A.D." that reads: "Meet me now," with a GPS location . She immediately turns and heads in the opposite direction of the store to her secret rendezvous with "A.D.". Once Aria arrives at the specified location, she makes her way inside a black limo, where she's greeted by a hooded person revealed to be Sydney . Driscoll is quickly exposed as a minion of "A.D.'s", seeing as Aria spots an ear piece on Sydney's ear that's being used to communicate with the person driving the vehicle . During their ride, Driscoll took credit for shooting Spencer, helping Jenna escape, and creating the board game . Sydney attempts to lure Aria into her tormentor's side, further disclosing that she's earned a piece of "A.D.'s" trust by agreeing to meet her in the limo . When Aria questions Driscoll's motives, she explains that working for their enemy means being a part of the "winning team". After being dropped off, Aria reunited with her friends but didn't mention anything about her run - in with Sydney . She received a text message from A.D. asking if she had made a decision about Sydney's offer . </P> <P> During "In the Eye Abides the Heart", the Liars are gathered at the Brew discussing Pastor Ted's mysterious photo of Charlotte and Lucas . Together, they wonder if Gottesman and Charlotte managed to stay in touch throughout the years . The girls decide to search Lucas's loft in an attempt to obtain answers, but Aria points out that the entire building could be bugged, considering his affinity for high - tech gadgets . Later, Emily and Hanna commence their search through Lucas's apartment . Hanna is quick to defend her friend, but while rummaging through a box of comic books, the two Liars come across a manila envelope tucked all the way in the back . Hanna reaches inside and pulls out another comic titled Arcturus . The author signatures at the bottom catches their eye, which reveal that it was conceived by Lucas and Charlotte . Aria soon joins Emily and Hanna, and they inspect the comic together . The content seems to be about a troubled boy who befriends a woman from outer space with magical powers . Together, they seek vengeance upon people who have hurt him . The girls can't help but notice that there are some eerily familiar drawings that resemble the electrical switches from Charlotte's Dollhouse . Almost immediately after this uncovering, Aria is seen on her phone, telling A.D. all about the comic through FaceTime . Back at the loft, Hanna pulls out the box where she previously found Lucas's mysterious comic, only to realize that it's missing .

Just as she starts to walk away after doing so, Aria appears to have a change of heart . She immediately doubles back to the locker, only to find a black hoodie hanging from the hook in its place . Spencer visits Marco at the police station to bring him a box of cupcakes and make small talk about Archer's severed finger that A.D. sent the authorities . Furey reveals that he spoke with a nurse at Welby and learned that Mary and Archer had an argument right before he went missing . Marco deduces that Drake might have been involved in Archer's murder, but his suspicions also lean towards Spencer . When Spencer returns home later that day, she immediately realizes that someone trespassed her house . Sure enough, the front door to the barn is ajar and a bottle is poised in front of it, with a note sticking out at the top . She unravels it quickly, only to reveal a message from Mary that states "Need to talk ." Spencer writes a response and sticks the paper back inside the bottle . The following day, Hanna pulls out the box where she previously found Lucas's mysterious comic book he wrote with Charlotte, only to realize that it's missing . Hanna immediately dials Spencer to inform her, but she dismisses her quickly in favor of opening up the latest note from Drake, which contains a single gold key . At night, Spencer unlocks a door at the Lost Woods Resort and stumbles upon a pile of mail right at the foot of the doorway . Suddenly, she hears a noise outside, and Furey walks in . He divulges to have followed her, realizing that Spencer was planning on meeting Mary at the motel . Marco shares that every theory he has about Dunhill's death somehow links back to Spencer and the other Liars . To make matters worse, Furey discloses that he ordered copies of Archer's paper receipts to inspect the signature . Spencer immediately realizes that she accidentally used Archer's credit card to pay for the drinks that she and Marco shared that night . Spencer proceeds to exit the Lost Woods abruptly . At the end of the episode, she receives one more note from Drake that says "You brought the police . I understand . Goodbye ." It turns out that Mary waited for her daughter at the resort but when she spotted Furey, she assumed Spencer had tipped him off . Mona is enlisted by Hanna to investigate the Liar's Lament board game after disclosing that Lucas canceled her friend's fashion business ahead of its release . Mona gets fascinated by the game's structure, and starts taking photos of the building . Hanna instigates Mona to play the game to find out how far "A.D." would go, but Mona insists she may end up getting addicted again in the process . Hanna is, however, able to convince her to play, stating that Mona will feel good when she realizes that she has defeated the stalker . Outside of town, Ezra is at the airport waiting for his flight when he sees Spencer and Wren Kingston talking . She immediately gets up and walks over to Ezra to quickly introduce him to her ex-boyfriend . Spencer then pulls Ezra off to the side and explains to him that she hasn't spoken to Kingston since before Charlotte's homicide . She met up with Wren in order to seek for enlightenment on his behalf given that he helped her former tormentor sneak in and out of Radley . </P> <P> In "The Glove That Rocks the Cradle", Alex orders Aria to destroy Alison and Emily's nursery, while wearing the black hoodie . She almost gets caught by Emily and is forced to flee . In Hanna's return at the game, Uber A makes her pick up something at the computer repair shop and bring it to Rosewood High . Emily realizes that "A.D." has a helper who destroyed the room while they were at the school . Spencer steals a flash drive from Marco . The item contains footage of Lucas admitting to the authorities that he wasn't Hanna's alibi on the night of Charlotte's murder and that the other Liars are capable of homicide . Gottesman is then shown clutching the comic book that Aria handed to A.D. and later spotted by Hanna awaiting someone at The Radley . He is finally caught by all of the Liars when searching through the contents of his apartment and they confront him in an attempt to learn more about his connection to Charlotte . Lucas claims to have been unaware that Charles transitioned into a female and took inspiration upon the narrative of their book .

During high school, Lucas disclosed to Charlotte that Alison bullied him and the other girls did nothing to prevent her out of loyalty . An anonymous individual proceeded to return the graphic novel to Gottesman, along with a note instructing him to meet them at The Radley or else his former friendship with Charlotte would be exposed . The person who gave him the ultimatum failed to show up, prompting Lucas to run back to his loft . As it turns out, Gottesman was concerned about a second graphic novel that had never been completed because it continued his first book's revenge storyline, only this time turning the events into a game . Afterwards, Caleb and Hanna return to Lucas's loft with the hard drive Hanna picked up based on "A.D.'s' instructions . The audio file contains a Patsy Cline song . Hanna remembers that "A" played a different Patsy song back at the Dollhouse .
