I doubt we'll know exactly whats going on with Chuck until the release, maybe Katey died but I like to think that as it's one of those What Ifs that they rewrited Chuck a bit, maybe he's going through a divorce and has started drinking (may explain why that achievement pic looks like he hasn't shaved).
