Gabby just makes her whole personality bad ghost puns and really existential lyrics (ones that could send a person spiraling if they aren't careful) once you actually read what they are. She absolutely makes punk/rock music.
Also, yes. Gabby and Crees poses on their album covers are indeed really similar. Sure this mean anything???
...
A little.
Gabby is what Cree could have been if it ever thought more about it's family's betrayal. (As in personality wise. They'd be rlly similar.)
