Middy did technically interact with them I think we he messed with our contract, but if we do still have the crystals maybe he'll start chucking them at us if we still silently nod our head at everything. Useless rocks right now afterall.

Also I'm just gonna call that we have a keyblade that was used to take Garuda's crystal but we still need to get a sense of our (character's) own self before it will actually manifest. Totally calling it.
