Ross confronts Ben about his not-so-secret feelings for Riley and tells him to back off; in fact, don't even come to the party. Not one to take orders, Ben crashes the party, but the night quickly takes a wrong turn when the boys get into a fist fight and a very drunk Tucker spills a few more secrets. Danny realizes he knows nothing about his new girlfriend, Ashley, and goes to great lengths just to find out her last name.
