He was fuming but I don't really get it. He expected some big reaction from Lewis, but Lewis would have been expecting to be up for eviction anyway, so the power didn't really "put him up" - all it did was remove his chance to play the Gamechanger, which he only had like a 20% chance of winning anyway? Even with Cameron playing to save him, it's less than a 50% chance. So it was hardly a big deal... putting him up there and then when there was a likelihood he would be up anyway.
If anything, he's probably saved Lewis some anxiety by getting it over and done with so that he can just accept he's up and relax instead of fretting about nominations results and the gamechanger etc
