<P> A year after her kidnapping and torture, she starts experiencing PTSD, something that Reid notices . When she is confronted by him, she asks him to provide a term to describe her situation, saying that it's more than PTSD . She breaks down and reveals the source of her PTSD to be Tivon Askari and reveals her miscarriage to Reid . She later takes an extremely large risk against an UnSub in a room with a gas leak, which could have resulted the deaths of herself, the UnSub, and a hostage . Reid approaches her in the BAU to tell her that while he couldn't find a term to describe JJ's condition, he called Emily and managed to obtain Askari's file, revealing his background of his life on the streets of Tikrit, Iraq, and his criminal background . JJ unknowingly hallucinates Askari in the room with her . He taunts her and tells her that he wants to watch her kill herself . He also tells her that he will take her sleep, her smile, and her safety away, as well as change her so that her husband and son won't even recognise her . He explains that the memories will eventually take away everything she holds dear, but JJ snarls a harsh "No" to Askari before realizing it was all a hallucination . </P> <P> Prior to her courtship and marriage to Will, JJ displayed little interest in dating . She once went on a date with Spencer Reid to a Washington Redskins game, but little came of it romantically, although the two became very good friends . In the season 2 episode "Jones", JJ first meets William "Will" LaMontagne, Jr. a NOPD detective whom the team worked with while in New Orleans after a serial killer presumed dead following Hurricane Katrina resurfaces . It is revealed the following season that he and JJ had been seeing each other for the past year but kept it a secret as she wanted to keep her personal life away from the prying eyes of her colleagues, which Will initially misunderstood as her being ashamed of their relationship . When she finally reveals their relationship by kissing him goodbye in her office with the blinds open, it is apparent that her colleagues already knew about them . </P> <P> In "The Crossing", JJ told Will that she was pregnant with his child . He later asked her to marry him, and indicated that he was willing to give up his detective's shield in order to help take care of the baby and allow JJ to continue to do her job, though he was worried about her safety and the safety of their child . JJ later told Hotch she had found a temporary replacement for the duration of her maternity leave, and soon after gave birth to a baby boy named Henry . Will transfers to the MPDC, and the family live together in Washington . In later seasons, toddler Henry is portrayed by actress A.J. Cook's real - life son Mekhai Andersen . JJ and Will named Reid and Technical Analyst Penelope Garcia as Henry's godparents . When JJ returned from maternity leave, she and Will had exchanged rings with Henry's birthstone, but did not seem to be officially engaged, as she wore her ring on her right hand, not the left . In the season seven finale, JJ tearfully asked Will to propose to her again, and they married the following evening in a small ceremony in David Rossi's backyard . </P> <P> JJ is very loyal to her family and friends, as well as very protective . She is also known to be a crack shot . This was demonstrated in many episodes such as "Nanny Dearest" by shooting a fleeing suspect in the head at a faraway distance . In "Revelations", she killed numerous flesh eating dogs in a dark barn . In "Penelope", she kills Garcia's attacker by shooting him directly between the eyes precisely as he turns around to find JJ behind him . Despite her petite frame, she is very athletic and has shown herself to be able to hold her own even if disarmed . In the season 7 finale, she manages to physically fight off a stronger and taller suspect who had tried to kill Will and took their son Henry hostage . She is best friends with Spencer (and is the only one who calls him "Spence"), Penelope, and Emily . </P>
