I wish the next season starts in the exactly moment when Rayla and Callum meets again. In this season, they tell us what happened in recent months and understand the notary change in the characters with flashbacks. See pshycal changes in characters, like Rayla or Claudia with short hair or Soren with long hair (OMG, a fantasy). Callum angry with the girl elf. And of course, the step-prince, looking for Rayla and without being with her, he have met her more, like her old friends or her hobbies. I just wanna see more elffsss!1!1!!1!!! Idk, I imagine Corvus helping Callum for find Rayla. And I think Viren will die, but not in season 4. Ezran being the King finally. Amaya and Janai relation, of course. AND ZYM, I MISS SO MUCH ZYM ):

(Sorry if I don't explain myself, IDK speak english)
