Woah! Where did that come from?

If it were me and I was in the heat of the moment I'd raise, but rereading it I'd fold. I don' think you can call because it looks like CO loves his hand and he will raise it and then it will be 2 back if SB raises.
SB could have 2 pair, trips or a straight which means your outs are discounted or you're drawing dead.
CO could have alot of hands but from the flop action he has a pp 99+ or A9.
Plus the fact that UTG loves to call he also taints your 2 pair outs.
After the weak analysis I still say fold
