Aubrey: Another job well done by Agent James.
His father, Philip Aubrey, was a high-profile stock trader, but was arrested when James was 13 for running a Ponzi scheme. When released on bail, he ran away to Croatia while leaving James and his mother broke and on their own. He revealed that he had a hand in arresting his father in The Next in the Last.
Aubrey: My father is Philip Aubrey. Maybe you've heard of him. He stole billions from his clients, so I know how this works. So you say that you don't have an account worth 4.6, because today the value might be 4.63 or 4.8. So, in your twisted little mind, you've told the truth. And if the account's in the name of some holding company, then you can honestly report that you don't have anything that belongs to Christopher Pelant and Associates. Now, you should know that I actually helped bring down my own father, Mr. Dunlop. So bringing you down will be a piece of cake. And as my friends here can attest, I love cake.
Physical Appearance Edit
Despite eating his weight in food, he maintains a fine physique. In The Lost Love in the Foreign Land, he told Booth that he has a blood sugar issue. Caroline refers to him as 'scrawny.' Jessica tried to motivate him to go on a "junk food cleanse" in The New Tricks in the Old Dogs, but he fell off the wagon after a day describing it as a sacrifice that a man should not have to make.
Aubrey: Huh?! Come on! I'm, like, a Forensic Food-ologist!
Aubrey is witty, smart, and clever, although he can break down. He can be arrogant at times. He also gets easily excited and can be described as eccentric; for example, he finds it easier to remember a specific fact when he is distracted about something completely unrelated. Early in his career, he tended to focus more on the implications of certain cases before recognising the human element, such as when he was enthusiastic about the potential of nailing a human trafficking ring before he saw the victims of the ring and realized the human element of the case. He likes children and is shown to be good with them as well.
Aubrey: (Looks at Christine sleeping on the couch) Aww. That is adorable. I gotta get one of those.
Season 10 Edit
In Season 10 Aubrey shows up as someone who Sweets trusts within the FBI. The deputy director of the FBI has Aubrey follow Booth around and make sure he stays out of trouble. Sweets immediately accepts him as a part of the investigation team, as do the rest following the death of the former as the season goes on. He is concerned of Booth, especially in relation to his gambling addiction. During the season he serves as a comic relief character of sorts.
In Season 11 Aubrey becomes more or less a full member of the team. Like in the previous season, the duration of the season consists of the Junior Agent being used as comic relief. But the mid-season finale starts with a body being examined in the field by Hodgins, Cam, and a few other policemen when a bomb goes off from inside the corpse. The blast kills 4 police officers. Aubrey grabs Hodgins and pulls him out of the way, shielding him with his own body. The shot ends with Aubrey on top of Hodgins, a pool of blood growing underneath them. Hodgins is 'fine', and is released as soon as they reach the hospital. Hodgins said he saw them wheeling in his partner and that it didn't look good. He was in surgery for three hours, getting seven pieces of shrapnel taken from his upper torso. Bones was very worried he would die, voicing her concerns to Booth. Aubrey wakes up to find that Jessica Warren had already visited him 2 times. He later sneaks out of the hospital to get in on the case, and earns a lot of concerned shouting from Booth.
In The Last Shot at a Second Chance, Jessica Warren was almost hit by a car, but Aubrey pulls her away at the last second. Afterwards, they share a very passionate kiss on the sidewalk.
In The Tutor in the Tussle, Aubrey has to deal with the return of his father Philip and whether or not to turn him in. Philip claims that he has a new family and needs Aubrey's help. Aubrey chooses to turn Philip in, having him arrested by FBI agents at the Royal Diner. Aubrey tells his father to never take credit for how he turned out as Aubrey became a good man in spite of his father, not because of him. Booth reassures Aubrey that he did the right thing and reveals that he has uncovered that Philip's so-called family was just another con he was trying to pull on Aubrey.
In The Radioactive Panthers in the Party, Booth allows Aubrey to take lead on a case which he is able to get a confession from. At the end, Booth reveals that Aubrey has been offered a job as a Supervisory Special Agent in Los Angeles and the case was a test to see if he could handle it as a result, Jessica Warren breaks up with him in The Day in the Life.
In The End in the End, Aubrey aids Booth and Brennan in finally stopping Mark Kovac. Afterwards, Aubrey reveals to Booth and Caroline Julian that he has decided not to move to LA after all. Instead, the same position has opened up in the Washington, DC office and he has accepted it. Having broken up with Jessica, Aubrey apparently turns his attentions to Karen Delfs who brings him some comfort food that he shares with her.
