I think we should also consider motivation, to be honest. Before tosay, none of the sheep knew the dire consequences of what happens to those voted out, so we had no real way of knowing just how much danger we were in. The wolves may have known ahead of time, and may have played more seriously from the start. That would certainly explain why Hans would be so quick to vote the first day, especially if Lockhart's team is a wolf team as well. Protecting allies and such.

Likewise we should look at who isn't getting as much attention. I do not know who knows who here, but I would think that if a wolf was a good friend of a sheep, they would try to protect that sheep.
