Tony goes to Agents Harris and Goddard with the names of the Arabs who used to hang around the Bing, getting the cell phone number of one of the guys, Ahmed al Najafi, from Christopher.

Christopher makes an effort to be social, hosting a large Sunday barbecue and dinner at his house with Kelli but Tony still rides him about not being around enough.

But Tony is convinced that this is the road back to college for AJ - frats and partying.
When Christopher finds out Little Paulie and Jason Molinaro have lifted more tools from Al's, he goes ballistic, busting in on a poker game and throwing Little Paulie out a window. Christopher goes to Tony to apologize for his rash actions and still doesn't get much sympathy, though Tony admits he needs to have a talk with Paulie. Meanwhile, Paulie is retaliating by doing donuts on Christopher's lawn, tearing his landscaping to shreds. Christopher calls Tony after their meeting to report how his wife and daughter were terrorized by Paulie but promises he will "sit tight."
