A/N: someone asked, "How would Ruby grow?" And I didn't know my self so here I am coming up with some weird way for her to grow!

Her body has metal bones. Those Bones have plates over each other. As she gets older the plates extend from each other making the bones longer.

Her Skin also changes! It kind of forms on her body! I imagine it looking kind of like Envy shapeshifting! (If you have watched Fullmetal Alchemist.)

I am not sure if this makes any sense but I hope it helps explain how she grows.
