Maybe it was the fact that she'd made it a point to keep an eye on her friends at home. Or maybe it was something else entirely. Either way, she'd noticed Frisk hadn't been quite... themselves? Not that she really knew a whole lot about them, but she remembered what they'd been like when she'd met them the first time. And it was clear that something was up.

At first, she'd figured it had something to do with the trip, so she'd decided to leave it alone. But then things didn't seem to be going any better after the first couple of days, and Marinette realized she should say something. Or do something. Or... something?

So when she glanced up to realize that Frisk had literally vanished, Marinette figured now was as good a time as any. After quickly excusing herself, she stood up, brushed herself off, and went off in search of Frisk.

She wasn't sure how long she'd been walking before she found them, but it didn't seem like a long time. When she did spot them, she just sort of stood there watching for a minute, apparently debating on whether or not she should really bother them. But then again, she'd come all this way and it would've been ridiculous to go all the way back now. And so...

"Frisk?"
