After pulling an all-nighter watching stolen cable, Louie is too tired to take care of Lucy, so he pawns her off on the neighbor, Ellen, just as she's leaving for church.

Kim comes home from work early to give Louie a break, but when she finds out where Lucy is, she freaks out — she doesn't want her to have church in her life. Luckily, Lucy seems to be on board: church was scary, she says, when Ellen drops her off. There was this guy, Jesus, and she didn't like him. "Jesus isn't real," Kim tries to assure her. "He's just a funny, pretend man." A disturbed Ellen quickly covers young Lisa's ears.

The following Sunday, however, Lucy is eager to head back to church "to give Jesus band aids and slippers." Kim and Louie reluctantly agree to take her. As a priest reads a dark homily, Louie sneaks off to a confessional booth to have a snack. Once inside, he finds himself unloading to another priest ("I'm a sh**ty father"), who ultimately absolves him — which makes him feel great. So great, in fact, that he sneaks off and returns to confession several times without telling Kim, who begins to suspect he's having an affair. When Ellen tells her she's seen Louie at church, Kim shows up and barges in on his confessional. "Is he fooling around on me?" she asks the priest through veiled window. The priest begs them both to go home and talk to each other, and they take his advice. But after a night of unveiling their darkest thoughts about each other, Kim isn't so sure it was a good thing: "I know so many things about you I wish I could unknow. But it feels good."
