Often, characters are written off of shows at the actor's request: crime drama fans may know that's the real reason Sasha Alexander left NCIS after season 2. But that wasn't true in Millegan's case.
During the filming of season three, Millegan was summoned to a meeting with Bones creator and producer Hart Hanson and writer and producer Stephen Nathan. At the time, no one knew the identity of the Gormogon — the serial killer with a taste for human flesh — and his apprentice. In the meeting, the pair revealed to Millegan that Addy had been pulled in by the Gormogon's ideas and was the one assisting him with the murders. (That turned out to only be partially true.) "It wasn't my choice," Millegan explained to TV Guide at the time. "It was a creative decision to shake things up and make a good season finale."
Millegan said that after clarifying that Addy was not a cannibal, he had mixed feelings about the revelation. "I tried not to focus on the fact that I was going to be off the show, and focus more on wow, look at all this great material they are giving me as an actor," he said in an interview with PR firm Andrew E. Freedman. We suppose that if you have to go out, you should go out with a bang... and, er, a possible link to a cannibal.
