Will we see Star go through Mewberty phase again or was it a one time thing?

Without spoiling anything for anybody, I can give you our general rule regarding developments like Mewberty. We don’t hit command z (undo) on anything of significance. We do, however, make sure that any elements that carry through have a reason to be there.

Will Star go through mewberty again? I can’t answer that. Will she be able to return to her butterfly form? Possibly. Look at the queen in “Game of Flags” and “Starcrushed”.
