So jus my own crazy thoughts here but Agent Char (introduced in Season 3 episode 4) is quite a lot like a maturer version of chuck. They both are analyst type Agents, both hate guns, they seem kind of similar and Char's name is even similar. Now I don't think the writers will do this but It kind of made me think of Char as a future Chuck and the bit at the end of Season 3 Episode 4 where Char is looking over an old engagement ring combined with his Anti-Love and Anti-Family speech means we know he's had a tragic love in the past.
Craziness Time: Time Travel... It just got me thinking that he could be Chuck from the future, I mean given all the similarities and the unexplained willingness to let Chuck handle things on his own (possibly to help him grow into a better Spy) all points to Time Travel in my head. Although I doubt the writers would take the story in that direction because Chuck has always seemed to lean more to the Spy Comedy rather then the Sci-Fi comedy it just made me think about it.
Anyone else notice anything along these lines or am I alone in my sci-fi thoughts... ? XD
