<P> Sarah (portrayed by Vanessa Morgan) is Jane's babysitter, and one of Ethan's best friends who he has a crush on . Although most times, she ends up babysitting Ethan and Benny as well . By the time the pilot movie begins, she is already a new vampire, bitten by her ex-boyfriend Jesse . Since she has not drunk human blood, she is only a fledgling, not fully human, not fully vampire . Hoping for a cure to become human again, Sarah tries her best to fit into high school and be a normal teenage girl, though she is unsuccessful . She refrains from human blood and instead, drinks a human blood substitute that Benny's grandmother makes . Sarah usually aids Ethan and Benny in their quests to defeat supernatural forces and has excellent fighting skills which, combined with her superhuman strength and speed, make her a formidable opponent . She struggles to keep her friends protected from evil vampires, particularly Jesse . In the first season finale, she finally turns into a full vampire when Ethan is bitten by Jesse and she drinks his blood to get the venom out . Although upset at first, she is later shown to somewhat accept what she is in the end . Later on Sarah begins to develop a romantic relationship with best friend and supernatural partner Ethan Morgan in the two part Season 2 finale, "The Date to End All Dates ." </P> <P> Benny Weir (portrayed by Atticus Mitchell) is Ethan's loud and goofy best friend . He is similar to Ethan, being geeky . He often gets into trouble with his antics . Benny has been Ethan's best friend since they were 6 years old . He and Ethan understand each other better than anyone else, although Benny is more funny and outspoken than Ethan . Benny can be just as brave and strategically clever as his pal, though he only showcases these abilities in the most dire of situations . Benny's dream is to make it big as a sorcerer and paranormal expert . He is told by his grandma that he is a Spellmaster and can cast magical spells, although his magic usually goes wrong due to his lack of practice . Benny often tries to lighten the mood when things get too intense . He is girl - crazy and frequently drags Ethan into his schemes, getting them both in trouble . Despite that, Benny is a genuine friend to Ethan and is always ready to go on another adventure . In season two, Benny begins to improve on his magic, becoming more helpful than in the first season . Benny secretly has a crush on Erica . </P> <P> Rory Keaner (portrayed by Cameron Kennedy) is Ethan and Benny's geeky, dimwitted, funny, non-genuse vampire friend . He is turned into a vampire after being bitten by Jesse at a vampire - infested party . No matter how odd Ethan and Benny are, Rory still manages to be the odd man out . He is even more immature than Ethan and Benny and has ideas that often gets him or all three of them into bad situations . Rory is a follower instead of a leader and has a major crush on Erica and is always eager to impress her, a trend which is in line with the traditional biter - bitten relationship . He is easily manipulated and does whatever he is told to do which leads him to become a full vampire (in the movie he says that his first reason for drinking human blood was because "everyone else was doing it"). Ethan and Benny mostly try to keep Rory out of their adventures, knowing that Rory can get himself into danger with his weak intellect . Rory includes himself nevertheless and though he can be foolish, he supports Ethan and Benny to the best of his ability . Embracing his new - found vampirism, he goes through several short - lived personae including' Vampire Ninja' and' Rory Vampire' . He's a fond lover of animals both as pets (he kept a cat called Mr Kitty and two alligators which he mistook for iguanas) and as a delicacy . In the movie he promises Ethan he'll not drink human blood again and sticks to this promise throughout the series only hunting animals, something other vampires including Sarah and Erica find disgusting, though he happily drinks bagged human blood again in "Blood Drive" and "Fanged and Furious" where he fights over a phial of it with Erica . In "The Date to end All Dates - Part 2" he shows courage (or complete stupidity) being ready to face a hooded menace until he finds out the intruder is his vice-principal, only at this point does he cow down and runs . He later displays his loyalty with Erica when he says that "if there's a fight coming I want to be here with my friends", he only avoids the battle when placed under Anastasia's powerful glamour . Rory's last name "Keaner" was shown on a computer screen in episode "Siren Song". </P> <P> Erica (portrayed by Kate Todd) is a vampire and Sarah's best friend . She is a huge fan of the "Dusk" series . (Dusk is a parody of the Twilight series) Erica becomes a vampire after being bitten by Gord (one of Jesse's friends) in the same vampire - infested party where Rory was also bitten .

Erica doesn't share an actual friendship with Ethan and Benny but speaks to them when necessary . She is annoyed mostly by Rory and makes sure not to be seen with him . However, she uses his crush on her as an advantage to get him to do things for her . Although Erica is conceited and shallow, she genuinely cares for Sarah and always comes through for her . In the first season finale, she supports Sarah after Sarah becomes a full vampire and tells her that they will (literally) be friends forever . In the second season, Erica becomes closer to Ethan and Benny as well, and subsequently becomes more active in their heroic activities . Erica seeks out Benny to help Sarah out after she dumped the new vice principal in a trash can, Benny doing a forgetting spell and gathers him and Ethan to testify against the Vampire Council's accusations . In "Say You'll Be Maztak", Erica helps Sarah get their male classmates out of a spell where they were controlled by Lucia, who wanted to be reunited with her Sun King . Erica seemed to be jealous that Ethan and Benny were all over Lucia, not believing that they were blowing her and Sarah off for her . In "Mirror / rorriM", Erica is controlled by a ghost trapped in a dressing room mirror during the school's production of the play, "The Rainbow Factory". Benny, Ethan, and Sarah manage to get the ghost out of Erica, in the middle of the play, the audience assuming they were performing . In "Village of the Darned", Benny makes a potion mixed with his blood for Erica and Sarah (because the towns' older citizens were possessed by an evil girl scout troop leaders cookies), Erica initially takes dislike to drinking blood from children and teenagers, citing it had fats; but Erica confides to Sarah that she liked Benny's blood, that it was "the best she ever tasted", and she might be starting to have feelings for him . In "The Date to End All Dates", while the vampire community is preparing to evacuate Whitechapel (in which Erica reluctantly and unwillingly helps them do), Erica helps Sarah and Ethan prepare for their first date, even choosing their restaurant, which was a vampire restaurant, where the staff assumed Ethan was Sarah's meal . </P>
