Byler being endgame wouldn’t have fixed the finale
Honestly, killing El off was the most offensive writing choice and byler being endgame wouldn’t have changed that. Making Byler endgame after that would have been bad optics and it would come off as them killing a female character off in the favor of two men so I’m glad they didn’t write it like that.
Our fandom is already hated and we would be even more hated.
El should have lived and byler should have been endgame.
