Turn Donk when board pairs dueces

[Langerz]

I think this one is pretty standard, but just a check up since I just moved back to limit. No reads just moved back to limit and didn't have many hands on the table, but since he open completed in the SB I assume he is bad.

Preflop and flop are standard I think. Who know what the guy has on the turn after an open complete and then donking the 2 on the turn. I suppose a 2 is possible, but a 8 or even a 3 or maybe some kind of pocket pair. Am I correct in just calling down? Not exactly wa/wb, but seems kind of like it and raising probably folds worse hands and just gets 3 bet by better.
