Sheila shows off her new girlfriend. Mick is still suspicious about Father Murphy. Tommy continues to hit on his half-sister, Mariel, and Johnny is both jealous and disgusted. Mariel says that she doesn't think they are related, because her mother was sleeping around. Garrity and Mike are still going to various twelve-step meetings to meet chicks. Franco asks Laura to move in, and claims that he's not seeing anyone but her. Chief's family convinces him to have a birthday party for Steve, Peter's partner. Chief invites all the guys, and they all try to worm out of it. Chief forces them all to go, and the party is super-gay, in the homosexual way. Garrity accidentally tells Laura about Franco's nurse/drug supplier, and Laura blows up at Franco and moves out of their apartment. Lou is still playing Candy against Sandra, and he seems to be choosing Candy. After throwing a huge tantrum in his basement, Chief seems to realize that his family is happy together and maybe he needs to get happy too. Tommy visits the burn victim kid and prays for Janet to come back. Burn Victim Kid wakes up from his coma. Janet slips through Teddy's crack security and shows up at the House of a Thousand Cats. It seems that Johnny tipped her off, because he doesn't think Tommy can handle parenting three kids alone. Janet and Tommy talk, and Janet reveals that she's had some counseling, and she's been remembering how happy she and Tommy used to be: she thinks they should give it another try.
Tommy and his kids are at the park, and the kids are arguing over which horse they are going to ride on the nearby carousel. Tommy snaps at them to stop arguing, signifying that perhaps things are still not going well on the parenting tip. Wait, did I just write "on the parenting tip"? I just got in a time machine and went back to 1992 or so. And I LIKED IT. Anyway, Sheila strolls up, arm in arm with a blonde lady. Sheila promises that she's not there to cause a scene (not bloody likely), and introduces the lady as her new friend, Debbie. Tommy surveys the two women snuggling for a second and then pulls Sheila aside and asks if she's kidding. Sheila asks, "What? I can't be a lesbian because you're so goddamn good in the sack?" Tommy spits, "No. You can't be a lesbian because we both know you love cock." Sheila claims she's changed, and Tommy asks if she took "a muff-diving pill." Sheila wants to prove her newfound love of the ladies, so she runs back over to Debbie and they start making out. Tommy's not impressed. Sheila starts caressing Debbie's breast. In the middle of the park! Some random guy behind them starts filming the women with his video camera, which cracked me up. Katie walks up and asks why Aunt Sheila is touching another woman's boob. Tommy rushes his kids away as Sheila, at least, looks slightly chagrined.
Tommy and Johnny both show up with bags full of clothes for Father Murph's clothing drive. Each is suspicious that the other is there with ulterior motives, if by "ulterior motives," you mean "hitting on your half-sister." Johnny accuses Tommy of stealing his donated clothes from a homeless shelter, and Tommy admits that it's true. Johnny says, "Rock bottom. It just doesn't exist for you, does it?" Tommy says he's trying to repay his debt to society, and Johnny says that Tommy has a long way to go in that regard. They hand their clothes over to Father Murph and his pal Ricky. Tommy very obviously asks if Mariel is around, and as soon as Father Murph says that she's not, Tommy finds an excuse to run out of there while also making sure that Johnny gets stuck helping with the clothing drive.
In the parking lot, Tommy sees what I assume is Johnny's car, since it has an NYPD sticker on it. Tommy steals a tiny plastic Jesus from the dash.
Tommy and Mick walk out of a meeting. As they walk down the street, Tommy asks Mick why he was "a million miles away" during the meeting. Wait, Tommy noticed someone besides himself? Mick confesses (heh) that he's been investigating Father Murph, and found out that the priest has changed parishes quite frequently. Continuing the tradition started with video camera guy in the first scene, this scene also has an extra who is just blatantly eavesdropping on Tommy and Mick's conversation, and it cracked me up. Tommy doesn't buy it. Eavesdropping Lady says that priests used to lock away young boys for sexual purposes, and the young boys were called catamites. Tommy and Mick kind of ignore Eavesdropping Lady as they cross the street. Tommy says that he saw a British band at CBGBs once called Catamites. Mick asked if they tried to give Tommy a blowjob, and Tommy says no. Mick says, "Different catamites."
