Mike was clearly overestimating his physical prowess going into the challenge - I think that Medical will allow him to stay in the game, but it's unlikely that he'll survive TC.
Russell's being an idiot in trying to push the tribe into voting out Betsy - she's clearly well-liked, and the other players will probably start to notice exactly what he's doing. The smart move here is to eliminate Russell before he has an opportunity to build up a stronger alliance and use the idol.
