Timmy was livid that his despicable, old boss let him walk away and then hire robots instead. Timmy was a good tech person and thought that his boss would hire him back.
He was wrong. His old boss said that him quitting is what inspired him in getting the robots. when Timmy chided him for letting all of his workers walk away (even if he did quit). He also said that he could have at least talked with everyone to find someone to program and fix the robots. His boss said he hired Jimmy to do it. Timmy swore he would impair the whole building for this. His boss said he wasn't adept enough.
