He hasn't said anything for the entire game, and only now he's saying that magically I have become the werewolf, you're a villager, and he's the seer. If I'm the werewolf, who is my partner? No wolves have been revealed. This is an internal battle, and you know it. There are flaws. My flaws are hidden, and my defenses are impenetrable.
If you're a werewolf, then your partner could be anyone. You could have been feeding us false information on one of the participants, saying he is a villager to draw the attention away from him. That's why your disguise would be brilliant, but easy enough to dispute if another seer shows up.
