Call this river UI?

[theflyingcow]

I've been trying this slightly more LAGGY preflop style recently. I got run over at this table which was full of LAGs. But at this point, I had no reads. My question, do we call this down without the nut flush? It seems like he's got at least 2-pair on the turn, which may or may not have been counterfeited. Thoughts?
