Dave is staring at John and finally John reacts. "Okay, what now?"
"I thought you were going to bring Teyla to this thing."
"Teyla and I aren't together."
"When you mentioned her the other day I kind of assumed that you were."
"Well, you assumed wrong." John knew there was a reason he never talked about this stuff with his family.
"I know what you're doing."
"Do you."
"Yeah, first there was Nancy, she made sense. And then Chaya, the hot yoga instructor. Then there was Teyla, who you never introduced us to. And now there's…"
"Larrin."
"Larrin. Who…really, John?"
"What is that supposed to mean?"
"It means that she's at a gala wearing a leather mini-dress."
"It's…" John racks his brain trying to remember what his date had told him. "Prada. Or Gucci. Or something like that."
Dave frowns, "Still. It's leather."
"I'm not seeing your point."
"You're afraid that things with Teyla are going to turn out badly. Just like with Nancy. So instead you bring around the yoga instructors and the…whatever it is that Larrin does."
He decides not to tell his brother that she moonlights as a roller derby girl. "What about you," John shoots back. "What model are you onto now? Calvin Klein? Ralph Lauren?"
"Shut up," Dave snaps. "Her name is Vanessa and we've been dating for two years. You know that." He shakes his head. "Good luck with the speech."
