Frisk seems okay with the physical contact. They shrug, but it's not in response to the weight of J's hand on their shoulder; it's just meant as a reply. Some people would say no. It'd be nice to think they wouldn't, but they're not that naive.

Rather than answer his first question in words, they flick through a few things on their phone before showing J a picture. There's not much of a family resemblance, so after a second they indicate Toriel. "Her. Him too." They also point to Sans.

They're aware the picture isn't what they look like now. But it's an easy place to start for them. People always have questions about the monster thing.
