Previously, Julia and the baby left Tommy for the dry heat of Arizona, leaving him to the wet heat of Lena and oh my God I did not think that metaphor was going to go there and I am so sorry. Anyway, Tommy finally broke it off with Lena, but not before she began to cultivate a Walker Plan B with Justin. Rebecca opened up old wounds with Sarah when she confessed her part in L'Affaire du Guitar Lesson, then opened up new wounds with Justin after she narced on him. And Kitty told Robert that she doesn't want to wait any longer to bring another McCallister into the world, and Robert figured that pretending he also wants to have a child when he really doesn't was the smart move.

Nighttime at the Walker Manse, and the collected Walkers (sans Rebecca) are helping Kitty pick out a song for her and Robert's first dance. The choices she's scrolling through on her laptop -- "From This Moment," "A Moment Like This," "Because You Loved Me" -- are all lacking. Kitty particularly takes objection to "Because You Loved Me" because it's in the past tense. I'd take objection to "A Moment Like This" because I'll be damned if the first dance of my marriage of going to be tainted by thoughts of Ryan Seacrest. Kitty laments that Robert's not that into the wedding planning because he's done it all before, and Justin compares it to "doing the steps a second time," which reminds him that he has to apologize to Rebecca. I'll say he does. Nora assures him that nobody's going to hold a person's intervention-day rantings against them. So...I guess that whole "turning a new leaf" thing where Nora wasn't going to coddle Justin anymore didn't take, huh?

Anyway, everybody has a suggestion for wedding songs, including Nora advocating for "that Dixie Chicks song," which Kitty shoots down because: Republican wedding. Kevin makes the salient point that ruling out the music of the damned leaves you with nothing but Ted Nugent, Skynyrd, and ZZ Top. Sarah says that, despite being a Democrat, she lost her virginity to "She's Got Legs." "TMI!" screams the family, in unison, as if the Latin word for "overshare" isn't in the family crest already. This leads to everyone reminiscing about the songs that accompanied their first times. Tommy's, for example, was the Dirty Dancing theme, which is rightfully mocked for its gayness. Justin refuses to share, but Nora's like, "Oh please, it was Pink Floyd's 'The Wall' and it was with Gabby Kliner in the tenth grade." Okay, first of all: "The Wall"? Hot. Second of all, either Justin wasn't discreet or Nora didn't keep The Tonight Show at an appropriate child-sex-drowning-out volume. Either way, not good enough. Staying in the dark about your family members' sex lives is something we all need to work at. Kevin says he has two first-sex songs, one with a girl and one with a guy. I wonder how he was able to get power to a CD player up in that treehouse at Ojai? Robert shows up before Kevin can admit to losing it to Paula Abdul and the original cast recording of Into The Woods, respectively, and they get him to admit that his first time was to "Endless Love." Everyone groans all, "Of course it was, Senator Too-Perfect."
