At the club, a boy named Steve watches Fiona from the balcony and seems bedazzled by her dancing. He'll do a skin-crawlingly overworked speech about it later, but it will still be confusing because she still looks pretty much like shit even when she's all prettied up to go out. A dude dances with her for a second and then steals her purse, and Steve makes all kinda messes trying to give chase. By the end, Steve and both girls are standing out on the sidewalk watching the gun run away, and being impressed by Steve's futile, heroic attempt.
Steve was going to buy Fiona a drink anyway -- at which Fiona bristles, because Steve's kind of posh and because it's what she does -- but then the bouncer won't let them back in. They didn't stop to get a stamp while chasing the man, and the bouncer's being a dick about it. There's a very pointy moment where Veronica and Fiona sort of surge at the guy, while Steve hangs back, like they get way too mad way too fast in this technically perfect simulation of what happens when oppressed people find a fight they think they can win and/or against arbitrary authority. The Harper Valley PTA effect. Or you know, rioting.
Anyway, Fiona is spittin' and pissed and the guy ends up barring them all -- but only after she intuits that maybe the bouncer is in on it. (Which: How would that work? "And then after I take their money, you refuse to let them back in the club. We'll be zillionaires!") So whatever, they're done and Fiona's now broke, so they're going to take a cab home... But first, Steve punches the bouncer so hard he falls over and then the three of them run off into the night so Steve can give them a ride back.
Lip lasts about five seconds, up on the bunkbed, before he can't take it anymore. He needs to talk about two things, with Ian, and one leads to the other. First, the blowjob from Karen Jackson, which Ian doesn't believe because Lip didn't tell him right away -- they're close, in age and proximity both -- and then when Lip asks if he's ever gotten one himself. Ian pulls out the pot, lights a joint. They're both grateful for that. It's never been this strange before, with them. With sex. Ian gets nervous but admits he has, a time or two. And so why didn't he tell? Lip produces Ian's gay porn, answers his own question.
