I'm watching from the beginning and have just made it into season 7 so jumping between that and season 15 is jarring. this episode was a glaring reminder of how far the show has diverged from it's original style and become a soap opera. maybe it will come into play later but i saw no reason for them to bring kaia back other than to try to tie up as many loose ends as possible before the final episode., which they can't possibly do so why not just give us more of the winchester brothers we started with.
