I will forewarn you Dimitri has toyed out loud (with me at least) with the idea of Mutinying as a way of building up relationships with more people. I have advised him to be careful about doing that, but he can decide what he wants in that regards. What you do with that information, I have no idea. But if he does end up on either of your tribes, he's pretty fun.
If you agree to watch out for him, I'll try to protect anyone that comes over from you guys.
