Outside of the house they would be great friends, but in the house, like you stated, cannot trust him, for sure. In saying that I would be extremely happy for either if those two to win, the rest need to go.
If it comes down to it though, tahan all the way
He goes back on his word much more than anyone else, its hard to really be his friend there.
I just dont think hes particularly close to anyone or anyone is to him after what he does and he/they know it.
Boog-Drew are closer than him-Drew or Boog-Tim. Tahan doing her own thing.
Though there is a group, its more for convenience for the game than a friendship to me.
