is QQ running into a hand here?

Would this be a stupid river call seeing as the board has paired? or am I ahead more often then not? The fact I was being called on previous streets screams to me that I'm ahead here(am I out to lunch on this?). After about 50 hands, villian appears to be standard TAG.

Looks like you only beat JJ here. He could've been drawing to flush too and bluffing river when you showed weakness. River bet is strangely small...
I bet $1 on flop. I probably call the river because he looks so weak.

Call. He wouldn't slow play AA/KK here and you'd prob of gotten re-raised pre-flop. He could have the 10 but I think he'd raise the flop to see where he was at and DEF of raised the turn. My guess is a busted flush draw and he's just betting because you showed weakness.
