quads would not have scared him. Occassionally UTG you will find players that limp big hands in hopes of raise, so that they can reraise. I am surprised that he didn't reraise you, however, he probably put u on an Ace and wanted to be able to get away from the hand if an Ace hit. When someone calls a big raise after limping, it's virtually always a PP, trying to take you down with a set....
