Could Ruby uses her sembalance to heal herself and reconstruct her body...or nah?
my dude. you have NO IDEA how much I WANT them the writers to make it something she can do. I mean if she can break herself and others down to the molecular level to go faster, SHE SHOULD be able to do so fucking much more there just healing. And the crazy thing is they can set it up perfectly by just having her read books in the background that are titled with that subject matter.
Didn't she say she liked books (I genuinely headcanon she was just trying to start conversation with Blake.)
EXACTLY! she looks books and comic books, it was a joke in volume 5 when drunk Qrow came back from finding Oscar she said
