25NL: TPGK on paired, 3 flush board

Thoughts on the river? I figured with such low aggro he's not betting that strong without a big hand, but he's so loose that I almost called anyway because air is definitely part of his range.

I like the fold, tons of hands with an eight or flush he probably does this with... what kind of air on Ace high flop?
