It's a possibility that Teresa might do something like bring Tom along on a RC trip, but I don't see it. I think Teresa is sophisticated enough (real estate agent, flight attendant) and has a husband, so I can't see herself putting up with Tom's antics long enough when he's got all the subtlety of a rutting moose. I suppose she might do anything out of desperation if she feels the oldBorans are going to pagong off the oldSamburus.
I think this has been touched upon several weeks ago, but it is worth discussing again. My feeling is that Lex-Ethan-Tom were a tight group back then (not so sure about that now) and Lex/Ethan KNEW they had enough to boot Diane and Jessie in the first two episodes and they KNEW that Tom went off on Clarence big time, so why not throw some people off the track by having Tom vote for Clarence? Stack the votes nicely in case it's ever needed (turns out it was never needed).
I believe that Lex or Ethan knew in S2 that Tina succeeded because of an unrevealed alliance with Colby, so they wanted to see if they could start developing such a thing with Tom to hide from the other Borans, see how far that takes them. Of course, MB is hiding a lot of alliance talk amongst the oldBorans so it is difficult to know what's going on and who's really with whom -- but this likely has everything to do with deciding who the final three is or we'd see some sub-alliances by now.
