QQ facing shove

Early Sunday afternoon 1-3-6...Main Villain has only $200ish to start the hand...table has been unusually limpy-passive, even though the HH promo for Sunday is on the lower end for payouts. Villain is a 30-something WG, friendly, big and kind of boisterous (not drinking)...he hasn't been here long, haven't seen him do anything noteworthy.

Villain limps the straddle, four limps to me in the SB and I raise to $50 with Q♠ Q♣. Quiet MAAG in straddle (also hasn't been here long, no read) calls(!?), Villain calls, others fold.

Flop ($150) 3-Way

K♣ 9♣ 6♣

I check, UTG checks, Villain quietly puts out a stack of $100...when I ask him to lift his hands so I can see his chip stack, he boisterously responds "Hell, I've got two of them," and holds both hands open, one of which contains the rest of his chips, approx. $35-40...

Hero should....?
