We know two things here:

Villain is a LAG with lots of money,
MP2 is short stacked.

I assume that MP2 has noticed that the raisor is also a LAG, so he might be trying to make a play here with a good holding, but not necesarily one that beats AA. And why wouldnt MP2 push here instead of min raising? It seems that the obvious move for him with AA would be to push since he only has $33 at the start of the hand. So, I am confortable in saying that he problably doesnt have aces but has some good-ish hand, hopefully with a high pair.

This leaves the question of the villain. Since you describe him as LAG I assume that he likes to gamble, also has some sort of quality-ish hand, and wants to take mp2 out. You and MP1 have shown no strength so far, so he probably does not consider you a risk. Plus, you would need a damned good hand to call a raise and a reraise. I wouldnt be to surprised to see two hands with lower pairs than yours, and maybe a run of cards by the villain.

I say you have to push in this situation.
