As soon as Kara started to talk about Krypton Barry's head straightened to attention, looking at her with interest before he gave a facial shrug that conveyed vague surprise. "I didn't know that other planets did that. I mean, I've never been on another planet before, so. I forgot that you were an alien. Wait, is that bad, is that insulting to say? I can't remember if I shouldn't say that." He winced a little preemptively, as if already prepared to apologize before a hand moved to scratch the back of his head.

"I mean, yeah, that would suck," he commented with a little laugh at the mention of raining lava. "That's something to be grateful for, that it's... not that, yeah. I think that we should probably do that again in maybe an hour or so, though. Check to make sure that no one shows up out there, I mean, just to be safe. Or we can try to find somewhere safer to stay because it's really starting to sound like the roof of this place can't handle the wind."
