You should be safe, a leader can only divert to someone with 50% of the lynchee's votes. Since reis and Yakman had 4, it can only be to me (3) or Nautilu (2). Or possibly to make sure only reis or Yakman gets it.
EDIT: seems it can't be the latter with these set of rules.
WoW, the leader role has changed since i knew it.. Didnt realise that.
Too be honest i hope he wasnt, as it just screws everything up if the Leader trait is used and not on Yak.
