Normally, if he's a solid player, I would have a hard time believing he checks KJ, AT, QT, AA, QQ or TT twice in a row on that board. 3bet looks like KT, JT, T9 or worse. I would say there's enough doubt here for you to call down. Reraising is not going to do you much good here. Call and bet/call the river unless it's a Q or A.

It really depends on what kind of player the "uberdonk" is. If he's the type to autofire when it's checked to him the raiser could try to be playing off of that, but given the board I really doubt he is trying to get that cute, since a lot of turn cards are trouble for him, no matter what he's holding on that flop.
