So far fusions have only happened with Amethyst in them (besides Stevonnie). Maybe this has something to do with it. Sugilite has more eyes. This could be a Garnet thing. Pearl, I don't know what her thing is.

If adding arms IS a Amethyst thing, then this would complete the Garnet theory. But it hasn't been confirmed, you can't use theories as evidence! I don't see him trying to.
