My own guess was that Cinder was a human/Grimm hybrid. My reasoning was that Nora is supposed to be based on Thor. Both Nora and Cinder wear a heart, but on opposite sides of the body. Loki was Thor's adopted brother, born a Jotun, but adopted by Odin after he slayed Loki's father. Given that reversalism in team JNPR, I carry that over to Cinder as well due to the Nora/Thor link. Hence, the name Cinder(ella) becomes another clue, since both Loki and Cinderella were adopted, lost a father, and had step-siblings.

Loki's mother's name was Laufey, which is often theorized to mean tree or leaf or pine needle. This would provide a link to Cinder's surname Fall.

In Norse myth, the Jotun were primordial beings who existed before the gods, and who sought to destroy the gods. This hints toward Grimm.

So if Cinder is actually based on Loki rather than Cinderella, then chances are she's at least half-Grimm.
