Here's what bothers me the most about the Blake Sibling fight: if Bellamy really is undercover (as people keep excusing) then why doesn't he tell Octavia?? I don't know how siblings work in the rest of the world, but I am as close with mine as it appears Bellamy and Octavia are/were and that's the sort of thing we'd tell each other if it meant staving off a beating (or even massive disappointment) from the other sibling. I trust them with my life and my secrets (on a need-to-know basis, of course). So, if Bellamy really is undercover, the fact that he doesn't tell Octavia about it is still messed up in my book. It's not like she can't keep a secret after being kept a secret herself for sixteen years. She's sort of a pro at that by now.

That makes me think he's not undercover and he simply screwed up big time.
