No phantom, I don't think you understand my point. I had already thought of the "what would an innocent do" thing.
Let us say Eomer is a werewolf, and lmp is another werewolf. Lmp steps in when the votes stand at Eomer 1, Kath 1, Esg 1, Oddwen 1, Saurreg 1. He posts "OMG, unless I do something four villagers will die. Ok, I'll vote for, um, Kath." How is that suspicious? And even if it is, how do we know if it is Esg, Oddwen, Saurreg or Eomer he is trying to save?

I got your point, however, about a clever werewolf thinking that a death of one of his allies would be worth it, as it was taking out four villagers as well. So it is as you said possible that one of the other werewolves had already been nominated too.

I've thought of another reason why werewolf-Eomer might have to save himself: if the other werewolves had already done their nominating when he was nominated. That basically means phantom and Celuinen (as I know I'm not a werewolf.)
However while it is perhaps possible that either phantom OR Eomer are werewolves, I don't think they both are. Phantom and Feanor, possibly (there's a bit too much Beatrice and Benedick in their rowing)
