Nah why do ppl hate on Crystalized?

Just finished rewatching Crystalized for fun (and to relearn all that section of lore). SHI WAS FIYAAA🔥‍🔥‍🔥. But now I'm confused, is Harumi ever gonna be in Dragons Rising? Like I don't see how she could, considering there's no plot reason Lloyd(or any ninja) would call her unless the Overlord comes back for the 354th time or some other situation they would need all their allies combined for. Was lowk pretty funny seeing Garmadon use a random ahh fern as a way to express his care for his son...
