Honestly I think we are about to see an evolution fest, I believe that at least Michael and Alice are about to evolve.
Maybe Amber/Liz too considering how fucked up Liz was at the end, I know she could turn into Amber and Amber apparently can shrug off damage like it was nothing, but i guess she couldn't because of the monster world water. Also there is a chance that they will evolve straight up to lvl 3 if twin evolution works properly.
However I don't think Mc will keep at the same lvl as everyone else, my bet is that his evolution will be the last thing at 1.0
