Those three sneak peeks seem to show Regina’s anger rising about the thing between Hook and Robin. They also seem to hint us the return of the Evil Queen and she might do in the end. And hearing what she wanted to do to Hook because it was unfair (very true) that he survives but Robin Doesn’t, she might (which may or may not) make a kill in the end of the finale. Yes she said she hesitated, similarly of how she felt for Maid Marian (Zelena in disguise), but it does not look like it will happen again this time. They are slightly repeating s4 in the second clip, but possibly they might do a repeat like Graham’s death in s1. This is getting very suspenseful. There may definately be a scary or tragic climax for the ending of the season like the former seasons.
They’re not gonna kill off Hook but I do expect by the end of the finale when Regina is all EQ’esque she is gonna set her sites on destroying Hook and Emma cause they’re at fault for her losing Robin.
We don’t know that yet. You do ‘t know that yet. And there is no way they are going to make the pair like the Charmings. If they’d kill him off, it could be for the very end of next season.
There’s no point in killing him off again immediately after he was brought back to life by Zues Ex Machina.
Tell that to the ratings. We’ll just wait and see.
