Becca and Vernon throw another party, this time to announce the sex of their child. Jimmy is upset that Gretchen won't take medication, and arrives determined to get as drunk as possible. Gretchen sets out to see what is so special about Nina. Edgar arrives at the party with Dorothy, intending to tell Jimmy he is moving out. Becca "accidentally" tells Paul that Lindsay is pregnant, causing him to have a crisis and setting off an attack of IBS. Vernon breaks into the bathroom to beg Paul for more money. Jimmy gets to his "angry drunk" stage and tells Edgar that Dorothy is manipulating him. Gretchen meets Nina at the bar and they bond over Jimmy's childish behavior. Gretchen tries to kiss Nina and is told to leave the bar. Edgar retracts his offer to move in with Dorothy, and she leaves in a huff. Paul believes he is the father of Lindsay's baby, and breaks up with Amy. Amy hits him, breaking his glasses. Jimmy reaches the "I love everyone" stage of drunkenness, and launches into a long speech to everyone at the party. Paul tries to reconnect with Lindsay, but she rebuffs him. Jimmy reaches the maudlin stage. He sees Edgar and tells him to pursue Dorothy. Vernon then confesses to everybody, about his fear of being a father, his emotional issues, his job, and his money problems. Horrified, Becca drags him inside the house. Gretchen arrives and takes Jimmy home. Paul sings a karaoke version of "Don't Know Much" after the guests have left, and Lindsay joins him in a love duet. Edgar finds Dorothy at the bus stop. She tells him it was just an ordinary fight and she is not breaking up with him. Paul and Lindsay leave in Paul's new motor scooter and sidecar rig, with Lindsay now looking horrified. Vernon and Becca are left in the ruins of their party. When Jimmy sobers up, Gretchen offers to get treatment, and tells him he said "something dark" when he was drunk. She then says, "I love you too".
