I think checking behind here is fine. Villian either holds a 5 or a Q, or less likely a PP like 88+ since he might re-pop you here (depending on your ASB since MP = CO 5-handed right?). If he's holding a Q, the only Q you're beating now that he reasonably holds is QJ. QT is one less hand you can value bet against now. PP's ('cept for TT of course) will now fold to a 3rd barrel. 5's will raise you. Basically he needs to be holding specifically QJ for us to make money here. Checking I think is the right play then.
