Danielle said it best on housecalls a couple days back, Dan's played one of the best games in all of Big Brother history. He does any move to out himself and does outlandish stuff and comes out unscathed. He's easily outplayed all of them, and is partly responsible for everyone on the jury's exit except Renny.
Let's review:
Swing vote for Jessie to leave, 1 houseguest.
Declared swing vote for Libra to leave, could've got the votes, 2 houseguests.(Keesha would've gone this week with votes from Jessie/April/Ollie/Jerry had Keesha/Dan/Libra/Renny vote out Memphis the week before, now that I think of it.)
Veto to send April out, 3 houseguests.
HOH to send Michelle home, 4 houseguests
Veto to send Ollie home, 5 houseguests
That's 5 out of 9 houseguests right now, and he's the HOH to send another home(though some might say that the veto is the only thing that matters this week) and he didn't even try 'til midgame. This kid is insane.
