i don't see how people are hating on cairngorm for how they're acting. given the circumstances it's normal, considering they were being controlled by their past self and forced to do everything against their will. they were given freedom for the first time, something that the other gems naturally had from the start.
i'm glad cairngorm is living lavishly on the moon and i don't blame them for smashing phos's head considering all the things phos made him do
