So it's a pretty common theory that Sans came here from Undertale, yeah? Here's my schizo theory: he didn't come alone. Flowey came along with Sans and is Ralsei, since soulless beings that enter Dark Worlds become Darkners. Ralsei can move between Dark Worlds on his own because he can...well, move around the Light World just fine. Ralsei is only partially an act since being a Darkner gives Flowey his empathy back, and he doesn't know how to deal with it. Double helping of schizo: Gerson is also the Undertale version.
