Personal Canon: G Callen (part 1)

Below is the first part of the really long winded personal canon I've been working on for awhile for Callen. It's pretty much just timeline. I've got more to say (which is why this is part 1) but it might be awhile before I get that stuff fleshed out. I'm putting this out here mostly as reference for me, but also because I get a little obsessive about this stuff and heck, it's my LJ and I wanna share :o)

A lot of this is speculation. I think I'm pretty clear on what I speculate and where what I think diverges from what other people have said, but I know there's some overlap and I may not have cited where I got all my ideas (can you tell I used to be a history grad student. Sometimes it really shows). Where I knew an episode that backed up something I said, I generally put in the title, but I think I did not get all of them. Anyway, feel free to ask me to cite my sources.
