Top two runs into heavy action.

fold

I put some more money in there when it comes back to me.

Re-raise and see what happens.

It might be trips but you cannot think that everytime someone re-raises you with AJ in their hand or a semi-bluff on the draw.

Raise enough to cut down the odds on that draw and let the villain know you are serious about things.

His reaction should give you a better idea of where you are.
