I like the smooth call 4th, donk bet fifth line much better than reraising 4th, even though the hearts are so dead that I am not scared of Seat 4 at all.

As for Seat 2's aggressive play, I've seen this before in that 6/12 game from people overplaying their hand. I think you have every reason to believe aces up will win the hand. The only thing I'd be afraid of is him having the case two aces.
