I think my default line here would be to bet the flop, call the raise, then bet the turn, calling down from there. Reasoning is that MP2 could be raising with a 4-flush on the flop. When MP2 raises the turn, it could mean some real trouble, but he could be on as little as an overpair, in which case your outs might still be good. I think the pot's big enough to justify calling down from there.
