20NL: 2nd pair vs. shorty showing weakness

[Genz]

Hey guys!

I need a check-up. I'm forced to sit with a lot of short stacks and they are generally terrible and force me into high variance decisions. I.e. they call any raise with any suited broadway and will get it in with any pair on the flop, either by calling, check/raising or even just plain donk pushing.
During the hand I thought of this guy as one of those short stacks. He isn't that short, but still short enough, so I guess I realized that he doubled somehow. Or at least he played donkish.

Stats are like: 60/22/1.7 over about 40 hands.
I put him on any pair here, any Q, ldo, but on the turn, I think there is a good chance that MHIG and that he is weak. Reasonable? Preflop is debatable, obv, but I usually don't 3bet TT oop preflop and I don't think I have any fold equity given my x-perience with the shorties.
