Christopher - S4-E3
Question: Was it Jimmy Altieri standing in the back of the crowd during the Columbus rally scene? He was killed in season one for being an FBI informant and here they probably used him as a stand in... If so, then that is some sort of mistake, because I think, it really is him. (00:15:50)
Answer: That's not Jimmy, just a look-a-like. Jimmy's short and stout, the guy in "Christopher" episode is tall and medium built. The hair is also different.
