Well he doesn't have 9s, but he is sure acting like he has an overpair - doubtful it's jacks - maybe AA - TT minus JJ.

I would fold QJs to a raise on the BB preflop...the minraise call is good but you didn't hit your flush on the turn...if you are committed to seeing the river you have to bet the turn pretty good since you hit a pair...

One possibility is that he is on the ace hi flush draw and he reraised you with position to get a free card...
