Villian is 26/18/2 over 220 hands. I suspect there is a possibility that he has been re-raising me light PF, but I haven't seen anything out of the ordinary postflop.

What's your play here?

I think if you do anything but call, Fnord will rub his asshole on you.

Without doing the calculation, a reasonable range has to include strong draws, Axs 9Js, made hands, and over pairs.
Either he's on the draw and is hoping for folding equity, or he's got 2 pair/set and is worried about getting stacked on a flush draw. Your read suggests a call, but it's very thin.
