 Booth had a difficult relationship with Brennan's assistant Zack Addy, as he finds Zack Addy's cold naïveté and social awkwardness disconcerting and, later, irritating.After failing to woo a colleague, "Naomi from paleontology", whom he was attracted to, Addy approached Booth for "advice" in the episode "A Boy in a Tree", much to Booth's annoyance and did so ever since.Booth has threatened to shoot Addy on several occasions out of exasperation.
