Relationships
As a psychologist, Sweets' initial relationships with the main cast are as that of an advisor and he often tries to help others, even when his aid is unwanted. Despite this, all of the cast has gone to him for advice, usually more than once and have developed some sort of friendship with him, although some (particularly Hodgins and Booth) view him as annoying. Sweets confesses that he had a secret thing for Angela at one point, mentioning in Booth's coma about Daisy, but Hodgins misinterprets it as love for Angela and replies: "Angela? You don't have a chance with Angela" but, after being intimidated by her father, he loses interest.
Despite his aptitude for behavioral analysis, he believed for a time that all the members of the team hated him and found him annoying due to their behavior toward him. However, all of them have come to him for advice at least once, a fact he has to be reminded of by Cam.
After Zack Addy was admitted to a psychiatric hospital for committing a murder, Sweets became his therapist and presumably sees him on a regular basis. Initially, Sweets believes that Zack does not feel guilty enough about murder and that he should feel less guilty about being taken in by Gormogon's rhetoric. However, in "The Perfect Pieces in the Purple Pond", Zack reveals that he is innocent of murder and simply provided Gormogon with information. Although Sweets wishes to reveal this to Brennan and Booth, Zack invokes patient confidentiality, knowing that he would be prosecuted as an accessory to murder and believes that he would not fare well in prison.
Sweets dated April, a tropical fish specialist, until she broke up with him in "The Man in the Mud".
