Brutus is the tenth episode of the third season. It was released on 24 November 2006.
The public assassination of a California senator leads the team to ethically and legally questionable experimentation on prisoners, the CIA, and a man bent on revenge. Elsewhere, Larry makes an announcement that shakes Charlie.
The reference would seem to be Mark Anthony's assessment of Brutus (and his co-conspirators), "Brutus is an honorable man, so are they all, all honorable men."
