I will be VERY interested to see how the group dynamic changes with Ellie gone. I mean, there are always some changes every week, but she was such a force in the group. I can't say that anything that happened today really affected who my top two Mole choices are (still Klaas and Rop). Both of them were suspiciously inconsequential in anything getting accomplished.
Although, the puzzles seemed to get harder as the climbing challenge went along, so Tim volunteering to go first and then confounding the solution of the probability puzzle could have been his way of intentionally screwing up early, knowing they'd need to get more of the later puzzles correct.
As far as the other topic is concerned (in no particular order): William S., Tim A., Tim H., Pieter D., Art, Patrick M., Dennis W., Dennis S., Coen, Taeke. These are mostly from memory, so I'm sure I've left someone out.
