Trouble on fourth?

I think neither opponent needs to have trips here. If I was still in with the ten up, I would certainly double bet with any hand here and test you. With you catching a two, its obviously less likely that the bring-in has trip twos. Nonetheless, I think it's quite an easy fold - your chances of improving are not great, and its very possible that you are facing trips. There's also the possibility of a number of raises going in here if either or both opponent is aggressive, and the bring-in at least appears to be.
