QQ multi way

ok so mp1 is a really passive donk hes like 50/1/20agg over like 30 hands. hes c bet like 35%. ive 3b him once before ip and he folded. I dont remember specific reads/stats on utg+1 but the table has been really limpy if you will.
I 3bet pre cause I dont wanna see a flop like 4 handed with QQ and cause most of these guys Im assuming will continue with like ax and smaller pocket pairs and maybe like tjs+.

Im not sure what do do on the flop when he bets 2.50 we have the Q of clubs. he can easily be betting this flop with any ace or like the K of clubs, a made flush or just cause. Im really not sure how this guy plays (or how to interpret his sizing) other than hes been passive and hes showing decent strength leading out with 2 people left to act. I feel like just calling is pretty bad given remaining stacks and we still have utg+1 left to act who could c/r this flop but idk hence the posting of the hand.
This could be really trivial but it had me semi confused.
