Ninjago and Nexo Knights (Kai x Clay shiping)

Ah ! What a good day to just relax and have a peaceful life, well, not until something go totally wrong on Ninjago and open a strange portal tô another world, where our ninjas have to stay with the knights : Clay, Lance, Aaron, Axl, Macy, Robin, Ava and Merlok 2.0

Will they be able to go back to Ninjago, or they shall stay on Knighton ? And will Skylor support having Kai away, and will Kai left Skylor for a new life with Clay ?
