Well he's gotta help the wolves for awhile in order to win as a couple. They were doing really well until Tommy got revived, now it's super over.
The way I see it going into last night:
Jawneh had to use the kill potion. If he uses it on a townie, it's instant game over anyways so who cares. If he uses it on a wolf, it's 4 v 3 if you assume that the wolves get a kill. But with two witches in the game a 4 v 3 isn't that bad, ESPECIALLY if you can say you were nightmared and that the witches should protect you so you can revive while you vote off a wolf. If you can lynch a non-Christina wolf in a 4 v 3 the game is over because then the cupid group becomes the dominant voting block.
Hindsight always makes these things easy though.
