I actually really like that they didn't just make callum and rayla simply get back together. I mean rayla left she did something wrong and both her and callum have acknowledged it and yeah there relationship is okay now but she left and callum was left and he was hurt so no his not ready to get back together with her and I like thst they have him that. Let them be friends again and now after just one season of being friends again there relationship is stronger and better than ever before so hopefully we can see them get back together with a stronger bond than ever before.
There is so much foreshadowing to Rayllum being the ones to bridge the gap between Xadia and the Human Realms, to end the conflict, and I honestly wouldn’t be surprised if we get an epilogue of their wedding.
“It’s an old wound that’s healing”. That whole conversation is just… their love is going to heal the world. And good for them.
