Yo what--
1: Selever is a half demon, Sky is a well-- idk at this point she just has a demon form
2: S is in so many FNF characters-- that's just dumb (Sarvente, Skid, Senpai, Shaggy, Spirit, Smiley, Swirl, etc.)
3: Selever had kinda a pinkish pale to his skin while Sky's shirt is a flat white.
4: Selever is 17 while Sky is either a minor or older, which would not work
5: They've never met canonically and prob never will
