"One Hour", Don expressed that he doesn't have to trust his team, they have to trust him. The exception to this may be Charlie, whom the therapist identified as a member of the team to Don's initial confusion. It appears that Don considers Charlie more of an extension of himself than a member of his team, which may be true: Charlie would likely not be involved in the volume of cases that he is if not for Don's continued requests for his assistance, despite the team's respect for Charlie's contributions. He also confessed to his psychiatrist that he "respects the Hell out of" Charlie for all that his brother does for the FBI, and that Charlie has never let them down despite often having the team's and Don's lives in his hands. When the psychiatrist pushes Don about his relationship with Charlie, indicating first that Don resents Charlie's presence at the FBI and then that Don enjoys having his little brother as his 'employee', Don vehemently snaps back and defends Charlie. This shows how far the relationship between the brothers has come, especially since being damaged by the unusual pressures of their childhood and the three months near the end of their mother's life that Charlie spent working on P vs. NP. The therapist reveals that Don has deep-seated fears of losing what he has worked for, together with self-esteem issues from growing up in Charlie's shadow and likely some abandonment issues as well. In "Money for Nothing", he acquiesces to the counselor's request to ask Charlie to come in for a visit. A looming issue was the day Charlie walked all the way home from a camping trip at the age of 8 (taken for Don's 13th birthday) just to get away from Don who did not want him sticking around. During the meeting, he learns that his brother was not as inept as he and his father thought and stated he likes working with Charlie. Both Don's therapist and Edgerton himself bring up the incident in which a suspect was tortured that nearly took Don over the edge ("One Hour" and "Pandora's Box"), but given the fact that it was done to obtain the whereabouts of a missing FBI agent, Don and Ian's superiors appear to be overlooking the matter for now. He was distraught over his father working with him in "Under Pressure", fearing for his safety.
