Kill him and we'll find out. You're using your day kill today or being lynched (this is obvious)
Since lawls claimed to have rolebased info here's what we do.
1) We get lawls to claim
2) You kill him (depending on claim)
3) If you don't we lynch you
4) Lawls flips scum = YAY
4b) Lawls doesn't flip scum we get confirmation of your abillity and probably alignment.
