Good news or bad?

I am playing a small S&G ($5.50) 9 person.  It is early and I get KJ offsuit under the gun.  I raise a couple BB just to make sure everyone playing is serious (and I am under the gun after all).  I get called by a couple people including the big stack (1.5 times the average).  He is batting 100% VPIP so this is no surprise. The flop comes 3A4 and I do a continuation bet of a couple BB.  Our new friend raises about 10BB and everyone (including me) folds.  I figured he has an ace. He is generous to show us that he has 34 unsuited for 2 pair.

I am grateful he was willing to play with 34o in the presence of a 3BB raise under the gun.  One of these times I will get his money (if someone doesn't beat me to it).
