If so it will be another case of the MCU-version of a character being an Inhuman rather than a mutant, since that's what she is in the comics (similarly to what they did with Eden Fesi). Although the comic character is also an alien-hybrid so it could be a case of her being an Inhuman because of her alien father (or mother if they decide to switch it up).
