I was going to post as general question but HH helps right?

If the board pairs and the action is on the paired street do I still get it in with the nut flush.

Villan in is a very loose caller, pocket pair definitely in his range. AJ,KJ,QJ 100% in his range too. No reraise so AA/KK probably out. I haven't seen him get it in without a hand post flop. But trip J's is a hand. He has calls largish (up to pot size) bets in draws/floats.
