QQ multiway, am I seeing monsters?

[benkath1]

UTG is very loose and very passive, I've seen him limp/call with AA-TT. Button is unknown.

My thought is this hand was someone must have some kind of draw. I was hoping my preflop raise would limit the field a bit, but it didn't. Am I a wuss on the turn, and what's my river plan?
