[Another curious soul. Barry finds himself relaxing a little as Lup's face lights up, her whole body language changing as she starts asking questions. It helps ease the discomfort he'd felt at a stranger joining him, interrupting his work, at being called a monster - he can let that one slide this time, she seems apologetic enough. Probably didn't mean to hurt his feelings at all. Unlike some humans, who still use that word as a slur, use it to shame him. Funny how beings as small and frail as humans can think themselves so invincible, so superior.]

That's-- uh, we're tryin' some different stuff out. Stuff that kinda is classified. It'd take a while to explain anyway, I think... [That's the awkward thing about studying something so inherently complicated as theoretical physics. Explaining it even to someone with a degree is hard.] What we'll do with it, I actually don't know. Gotta figure out if it's even there first. What it can do, what interacting with it and movin' it around would even mean. Y'know?

[Barry laughs again, that same deep, gentle sound from somewhere far inside his huge body.] Controlled explosions can be real fun. Astrochemistry though, huh? That's interesting. Lotsa fascinatin' stuff got to do with molecular gas clouds and radiation. We study that a lot at th'lab.
