Well, you know what went wrong here, it seems. You can consider folding 3rd, but after that you should be going to the river (especially since the paired door is already all-in).

What do you put Seat 3 on that you think beats you? You hold a T in the hole; he isn't showing a card higher than a Q (and you have the other two of those, so he'd have to have the case Q or case T to beat you); he showed no aggression on 3rd or 4th, so there's no reason to think he has A-A or K-K buried. I think a low pair in the pocket or something like A-K spades is the most likely. You have to call on the river. As it turns out, he had total junk.
