Dance. Cate and Math watch the teens go inside and snark about how skanky they all are. Lux approaches, and Cate immediately wonders what's up with her shoes. Lux runs up while Jones checks in and snits at Cate for being there. Cate promises it'll be like she's not even there. Jones arrives and gives Cate a chipper hello, only to have Lux sulk off without a word. They head inside, and Jones asks Lux to dance. And by "dance," I mean bounce around seizure-like and occasionally throw a hand or two in the air. It's like he watched Napoleon Dynamite and "How To Dance Like a White Guy" and thought, "There might just be something to this!" Yikes. Just like she inexplicably loved the pink dress, Lux laughs hysterically and joins in on the a-rhythmic flailing.
Somewhere near the punch bowl, Math listens sympathetically as Cate bitches about how brutal high school was. She wonders if this was a bad idea. He reminds her that 16 years have passed, that she's not that girl anymore. Then he adds, for his own ends, that he's not that guy, either. She breathes a sigh of relief that at least Baze isn't there. Oops, spoke too soon! Baze walks in, looking dopey as ever as he searches for Lux and Jones. Cate spots him first and cuts him off at the pass to ask why he's there. He asks her the same. She says she's chaperoning and calls dibs on this night. Baze (who is wearing a T-shirt with a keg that says "Tap that") calls her immature, then insults Math's corsage. Math intervenes to steer the ship in the right direction. Baze lies that Lux forgot her purse. Cate tries to snatch it from him, but Baze smugs that he's going to take a walk around and "relive [his] former glory." Their arguing gets loud enough that Lux notices them both there. Jones sees she's growing tense and asks her if she wants to go outside. She says yes. Baze follows them out. And just as Math is about to ask Cate to dance, Cate joins the bandwagon, too.
Outside, Jones commiserates with Lux about embarrassing parents. She fills him in on the back story of her conception. Just as Jones starts to understand the weird place she has to exist in, Baze rips open his door. Jones swears they were just listening to music. Baze says, and I quote, "Right, right, I know where that leads. A little Spin Doctors, some Zima, the next thing you know you've got a crazy chick tracking you down a football field holding a stick that she peed on!" While Cate processes that beautiful summation of their lovemaking, not to mention figures out why Baze is so freaked out and where her sister comes in, Baze gets increasingly intense with Jones. He even tells him to address him as "Mr. Bazile," which is pretty awesome, albeit wildly inappropriate for many obvious reasons. Finally Lux drops the bomb that it was her condom. One that she planned to use with her recently returned good-for-naught boyfriend Bug. And by the by, she's not a virgin. She nearly moved in with Bug, as we well remember. It's so obvious to everyone but Baze and Cate, ironically. Having just been handed a pile of information, Jones joins Cate in the "Who in the what now?" chorus. He appears to still be repeating it in his head as he skitters away. Then Lux tells her parents they both suck equally. Which is to say a lot.
