Patti LuPone busts back onto the scene as Frank’s mother, Silvia, who is pissed but mostly thrilled that Frankie and Liz are in love. Unfortunately, Frank’s girlfriend Lynn (Susan Sarandon) is under the desk and the truth will come out, putting Liz in the middle (of a mouse pile). Meanwhile, Jack teaches Kenneth paranoia and gets a visit from Stanley Tucci and Jenna and Tracy solve the mystery of Pete’s missing whisky in time for a birthday miracle.
