Help me to not suck deep

[Double Eagle]

This hand came up at the end of my session this morning vs Frink. He's been playing his normal wide open style and views me as a bad nit. I got my chips by stacking him 20 minutes earlier with JJ vs TT aipf. I also just stacked him on another table when I beat his flopped straight with a set that made a boat after the chips went in.

Edited to add: For those that don't know him, Villain is super aggro/borderline spewy and very good at reading hands.

Two questions here, should this be a snap call on the river and what should my line on the turn be?
