Beila adopts a strategy of completely ignoring this insinuation until an interviewer asks her point blank, at which point she says, "No," and declines to elaborate further. Because there is nothing to elaborate on.
She shows up, exasperated, for her next firebending lesson.
"I definitely in-my-dreams want to," he says. "And, you know, it is a thing that could hypothetically happen. If you were okay with it and everything - I'm not going to cheat on you either. And I'm not completely sure that I would actually try it even if you were. But - now I'm thinking about it."
A couple of days later, when they're hanging out with milkshakes on the roof of the milkshake place (because roofs are awesome, that's why) Beila says, "So, I think I could pretty well live with it if you wanted to sleep with other people, as long as I knew who it was ahead of time - no surprises - and I wasn't neglected or anything."
She's been progressing pretty well in her studies, picking up more and more of the basics and putting them together with increasing complexity. Jun encourages her to take it slow and pay attention to the element, to put as much precision into her form as she can manage, and to take a break every so often and think about what she's learning.
"Your control is improving," he comments at one such interval. "Faster than I expected, with that precision issue you have. Good work."
"I can tell! If you keep it up, in a few weeks I might teach you how to do wings. You'll want very good control for that, for obvious reasons, but it's not that hard if you can get the trick and there's limited potential for disaster down here even if you screw it up. Plus it'll be a good way to get further practice in keeping your air separate from your fire. Does that sound like fun?"
"I'd want to be really sure of not setting my glider on fire, too, and not have my boyfriend with me, he'd squeak more than Liqing would if I surprised him. I can probably fly glider-free if I figure out how to activate the Avatar State, but I don't have that down at the moment."
"Yeah, only prearranged fire with the boyfriend. I believe it was shortly after I met him that I actually, in words, promised not to lob a fireball at his head. It was my first day with waterbending, I flicked a droplet at him." Pause. "Oh, by the way, he has a crush on you and I have his permission to mention this so he doesn't have to figure out how to say something himself."
When he spins out of the ashes of the red kilt, there turns out to have been nothing else underneath it.
The audience is mainly pleased with this development.
