>>105316482> Three episodes gives no time to fully soak in why pink ditched it all in the first placeWe had solid knowledge of why she left it even before this HW arc started. The episode from the OP pic spelled it out pretty clearly, even if it WAS super short.
Pink was bored as hell because as a diamond she can't go and have fun or do anything, she goes to earth to see her little colony come to life, gains an appreciation for earth, tries to get it taken off the colony list, fails, and so she leaves.
