It's exactly what that sound bite said - he's a kid trying to prove he's as seasoned as the older players.
to be fair to him, he was going to have to take Zeke out at some point fairly soon. If he waits too long he wouldn't be able to get enough votes to take him out. The crappy part for him is that Ken was such a freaking moron.
If David tries to vote for him, he's a bigger idiot than I thought he was. Use him for one more vote, then vote him out.
