I dunno, somehow I found this ep lacking too. Everybody was so busy double-crossing and contingency-plan making that I found it hard to invest in anything that was going on as I was just waiting for each piece of action to be consistently undermined - which it was.
I also don't understand what Stefan gets out of the coffin-stealing bit? He's just setting everyone up to die and for what? I mean, either immolate the family or bury them in cement but to play "come and get it"? Why make everyone a target that way? I don't follow.
I mean, I get Katherine's motivation - get Klaus chasing someone else for once besides her. But for Stefan it seems a pretty stupid move.
