[Someone saying it like that, so plainly, seems incredible to her. She's about to reply that she couldn't imagine doing something like that, but Alphys has to stop herself, because... she has. She has done things like that. She's seen how gorgeous the pools around the gods' temples were in the desert, she's felt the ocean breeze on her skin, she's seen the lights in the sky under the snow. She's been there. She's seen something.

It's a surreal experience, and not one she knows how to really speak about, nodding a little as she listens and tries to put all this together.]

I... I guess I've seen some worlds too. Just being here. I mean, I didn't go alone, the w-whole city came with us, and we didn't really have a choice, but... it was amazing. There's been scary stuff and aliens and all kinds of things we uhm, we couldn't control, but... h-heh. That's probably not what you were talking about.

[How could she compare herself to someone amazing like her, like a real hero? Alphys is just surviving. There's a difference, somewhere, she's sure of it.]
