Votekill Gary
I really believe David tried to recruit him (agreeing that there's a good chance he died during the recruitment).
In Gary's first game, they were both Mafia (Pokemon Game). They won and did a pretty good job, both of them.
Then in the following game, Gary was mafia again. You were the recruiter, got me, then got DD, and after it, went for Gary and died. I don't have the piratepad anymore, but I believe DD either recommended that to you, or we talked about it and agreed all on it. So I think Gary is the one DD would see as the most valuable to have in his party.
I do suspect you a bit for crossing him out so fast, tho. Others I still suspect are Kat, Ao and Gol, just to mention.
