The series' main characters consists of the fictional Jeffersonian Institute's forensic anthropology department staff members Dr. Temperance Brennan, Dr. Camille Saroyan, Angela Montenegro, Dr. Jack Hodgins, and interns Zack Addy, Clark Edison, Wendall Bray, Arastoo Vaziri, Daisy Wick, and Vincent Nigel-Murray; FBI agents Seeley Booth, Dr. Lance Sweets, and James Aubrey; and Justice Department prosecutor Caroline Julian.
Pelant seizes control of a General Atomics MQ-9 Reaper and aims it at a girls' school in the Afghan province of Kandahar while simultaneously draining all of Hodgins' financial accounts.
By the season ten episode "The Verdict in the Victims," Aubrey is shown to be a fully accepted member of the team, eating Sunday dinner with Booth and Brennan and occasionally baby-sitting Christine.
(Earlier he was lucky to escape possible lethal infection by quickly putting on a gas mask after Dr. Saroyan cut into a concealed glass bulb while examining Caroline Epps' head).
His way of working leads Hodgins to think of him as subjective, long-winded, and lacking the qualities of a pure scientist; however, the antagonism between the two develops into a friendly rivalry as the season progresses.
Clark continues to open up in "The Body in the Bag", he reveals that he comes from a large family (nine brothers and sisters, and that he could never get a word in with them) and that his parents traveled away from home a lot (he speculates that he has abandonment issues because of this), all of which he attributes to his being so withdrawn and private.
In season 7, Clark appears in two episodes, "The Male in the Mail", where he gets awkward around Brennan and her pregnancy, and "The Warrior in the Wuss", where, concerning the impending first meeting between Parker and baby Christine, he brings up the fact that there are many myths about the dangers of step-children.
Wendell is portrayed as one of the more "normal" interns; he lacks the social ineptitude characteristic of the likes of Daisy Wick, Oliver Wells and Zack Addy and is often heard cracking jokes with Jack Hodgins.
Fisher returns in "The Twist in the Twister", in season 7, and reveals that he has recently had a stay at another mental health facility, "Verdant Valley" (which he says, as "nuthouses" or "loony-bins" go, he gives a personal rating of "4 out of 5 nuts; fantastic game room, but the nightgowns chafed"), and that, as a condition of his release, he is living with his mother, who, although has yet to make a physical appearance, is put across as chipper, the opposite of her son, and who causes him bother by constantly phoning him at the Jeffersonian.
Although he doesn't appear in Episode 20, "The Pinocchio in the Planter", he is mentioned by fellow intern, Wendell, according to whom; "Arastoo's family's loaded", when he put forward his argument Dr. Saroyan as to why he needed the extra hours in the lab.
They keep their relationship secret from all but Hodgins and Angela until "The Survivor in the Soap", and in "The Pathos in the Pathogens" (season 8 episode 23) she openly admits to being in love with him when his life is threatened with an altered strain of virus.
She has the propensity to be irritating and annoyed the entire team, including Booth and even the usually calm Dr. Brennan, with her poor impulse control, lack of consideration for the personal space of others, non-stop talking, and inadvertent insensitivity; eventually leading them to fire her twice.
However, in the season 9, while he is brilliant, he is also shown to lack tact, and he is believed to have a bit of a superiority complex, much to everyone's dismay, has a rather abrasive personality, and is also one of the few interns who regularly (and often obliviously) gets on the nerves of Dr. Brennan and their boss Dr. Camille Saroyan.
Filmore's latest appearance was in season 9, "The Master in the Slop", where he is participating in an American-Canadian trans-border study of co-operation amongst forensic scientists, on behalf of the FBI and the Royal Canadian Mounted Police; here he also shares that he grew up on a (pig?)
After the death of Kovac, Caroline promises to ensure that his sister will be spending the rest of her life in prison and is relieved to learn that Aubrey has taken a job in Washington rather than moving to Los Angeles.
He also reveals his past as "Noddy Comet", a glam rock guitarist, who "wore spandex, pancake makeup, silver lamé and played a guitar shaped like a spaceship".
Dr. Wyatt celebrates the good news with Booth and Brennan and his help in finding the body proves instrumental in securing Zach's exoneration on the murder charges in "The Day in the Life".
At first, Brennan doubted his sincerity because of his wide variety of interests and hobbies—he has a minor in kinesiology and a major in art history, is a certified EMT, a finish carpenter, and a criminal profiler; but Booth assured her Sully is serious about his job and mentions he lost his previous partner.
Russ resurfaced during the course of "The Knight on the Grid", in season 3, after learning his stepdaughter Hayley had been hospitalized again with complications related to her cystic fibrosis; he was arrested by Booth and sentenced to thirty days in the county jail, with the term of his probation extended and amended to include the wearing of an ankle monitor.
A former lieutenant commander and intelligence officer in the United States Navy, his first appearance was in the fourth-season episode, "The Con Man in the Meth Lab", where he arrived in Washington, D.C. to take a new position at The Pentagon.
After much persuasion from Dr. Brennan and the "squint squad", he agreed to help them access a critical piece of evidence (i.e. steal it from the FBI) under the pretext of a "classified" military intelligence operation and Hodgins was able to deduce where Booth was being held captive.
It revealed that Jared has since been court-martialled and dishonorably discharged for "misuse of authority" and "theft of government property" after he aided the Jeffersonian team in stealing a critical piece of evidence to save his brother's life.
Epps' second appearance was in the episode "The Blonde in the Game", where he is still in jail but has been directing a copycat accomplice, leaving clues for Brennan and the team to solve to lead them to the next victims.
In the Season 6 episode "The Bullet in the Brain", Taffet requests Sweets to accompany her on the way to court for a final appeal and she indirectly tells him that he is the "weakest link" in the food chain in an attempt to sabotage his confidence before the trial, which she does successfully.
[27] He also developed a personal agenda to assassinate anyone he believed didn't deserve to live, and was willing to kill innocent people who got in his way or defied him (referring to their deaths as "collateral damage").
After first planting a corpse above Angela and Hodgins' bed, Pelant infiltrates a private military company, hijacks a Predator drone and programs it to attack a school for girls in Afghanistan.
Pelant makes his final appearance in "The Sense in the Sacrifice", where he turns the Jeffersonian team's plan to "flush" him out against them by murdering Booth's colleague, Special Agent Hayes Flynn.
The Ghost Killer is first alluded to in "The Sense in the Sacrifice" by Christopher Pelant shortly before his death; he states that he may or may not know the individual personally, but has "reason to believe that she is a woman".
The team realizes that Kessler, who had been in prison for twenty years, killed McNamara to settle his score; his reasoning was that she wouldn't have been brought to justice due to her powerful family.
In "The Daredevil in the Mold", Booth, scared of being alone for the rest of his life and spurred on by a night of drinking with Sweets, proposes to Hannah, who gently turns him down, telling him that she is not the marrying kind.
