Sorry, no hand history but basically:

I just sat in the game, Me and UTG both have full stacks. I have seen UTG overbetting a few pots with TP earlier.

UTF limps, it's folded to me in BB and I check in BB with

FLOP
(Pot $1.25)

Hero bets $1
UTG minraises $2
Hero reraise $5

UTG writes in chat:
-What did you flop ? T-3 ?
Then reraises to $15.

Hero ?

Comment: I actually chickened out here due to a couple of previous beats where I had been up to sets, UTG showed me his hand afterwards though.
Also I was surprised as to why UTG would reveal his thoughts to me ? tricky one...

well he isn't really worried about you having T-3, in fact he comments on it and raises.

I think he has a set

fold, people talking like that and raising is not a good sign.
