Frank is about equally pissed that Monica fucked his brother and that she did PCP in the summer of 1995, without him. Everybody talks and talks and yells and yells, and of course it's all about Frank, and of course it's all about Monica, and of course it's not about Liam, not about Fiona, not about Lip. Certainly not about Ian. Lip does get to say how proud he is of Monica playing to character by cheating on their dad, so at least somebody's swinging, but I really think since this is Fiona's like entire deal, maybe she could have had more lines. (Or maybe, actually, this is a conscious production decision to demonstrate how the brash no-bull Fiona got roped into any of this stuff in the first place: Her mother is her one Kryptonite thing.)
Suddenly Frank's talking about how he and Monica are supposed to be together and shit, and "you know how much I love teddy bears," and Debbie's explaining lesbian sex to Carl, and they're talking about divorce and Monica might marry Bob, and it's so boring. Although Frank does get to say "Cut the shit, Myrna Loy!" which made me laugh. Anyway, Monica runs through everything she's ever said, one more time, and Fiona points out that being an unhappy wife is actually different from being a shitty mother, and when she leaves the rest of the kids follow. Sadly, they do not set fire to Aunt Ginger's house with all three grownups inside. (Karen still might, though. She is on a tear.)
You know who is really on a tear, though? Sheila. She finds Eddie crying at the dining room table, and he whines about what Karen did to him, and Sheila loses it.
Sheila: "She deserves love, not hate!"
The end. The only possible end.
Sheila harries Eddie through the kitchen and into the living room out into the foyer and out the door and into the yard and into his car and then she waves her arms at him, sitting in the car, screaming the entire time, and screams, "Don't ever come back! Forever!" until he drives away. And it takes Frank, having deserted the sad dinner, to point out that she's standing not just in the yard but in the street, outside the house. Free. She calls hello to the night, and to the people on the El, and I can't wait to see what happens now.
Hiding out in Steve's house, the kids see Monica and Bob packing up, and they wonder if they should report her for kidnapping, and then all the kids run out into the yard and there's Monica, crying just to beat the band, and she hands Liam over to Fiona and the music gets very Friday Night Lights and annoying, and Monica sobs for like ten minutes and then there's a cheesy acknowledging nod from Fiona and everything's going down in big gay flames and Monica sobs against the window of the truck, hilariously, in a cloud of her own breath, and this is what we call caulk over a split seam, because what could have been a good episode and a fairly powerful ending instead just feels like a cartoon, and then just to help you get over the complete lack of feeling you're feeling right now, there's some racist kitsch about an Asian blowjob hooker impersonating Monica at the City (County) Clerk's office, and finally this bullshit episode is over.
