Hitting top set on three flush flop

[MikeSmith]

I cant find my hand history so you will have to bear with me....

4 players in pot early on in a 1 table tourney...

blinds 15/30
Relevant stacks
Villain(mp2) 800 chips
Hero(button) 800 chips

Hero dealt 88

All Fold to Villain who limps, folded over to hero who bets 90, both blinds call and villain calls

Flop 8c7c6c (Pot 360)

All check to hero who bets 200, blinds fold, villain reraises all in...


Hero????

This is one scary ass flop for top set, whats your line?
