I dunno if he would, it would be like Mike taking the fake idol to tribal and not the real one, playing the fake one, and saying, oh, let me go back to camp and grab the other one
LOL this is a great hypothetical but I think amf7410 pretty much pegged it, that would be going back to camp. in the past when people have shared idols I told them they could leave it back at camp and one person could still use it, so back at camp makes it out of play for tribal.
