Lily: What I'm wondering is why Frisk-FRISK-Of all people would do that. Sounds more like somethin' MTT would do if y'ask me.

Chara: ... I could see it in the kid's expression. It wasn't the pacifist I knew in the timeline before. No... some weird force was there. Controlling him like a puppet on a string. Except... he wasn't. Frisk was doing this on his own. The force... Mettaton... was just guiding him.
