I know I keep going on about this but if Kitsis and Horowitz have stated that Blue is good and only wishes to to good then I’ve got to believe what they’ve said. They weren’t ambiguous about it. They made it perfectly clear she is good and only does good.
Who knows why she didn’t offer up other methods to Rumple in order to follow Bae. Let’s be clear about it. Rumple let go of his child’s hand. Doesn’t matter if he regretted it after the fact. He still chose his power of Bae. Maybe there weren’t any other methods around back then. Maybe the wardrobe is something Blue developed centuries later just as Rumple developed the curse many centuries later.
She didn’t lie to the council about only one person being able to go through the wardrobe. Gepetto had already betrayed everyone by forcing her to agree to allow Pino to go. Thus, she spoke the truth to the council as only one could go through the wardrobe. She just didn’t divulge the deal she made with Gepetto. Why would she? It would only cause further dissension among everyone when what they needed to do was come together.
So, going on the fact that the creators/writers have ruled out Blue possibly being bad, the only way she could betray everyone is if it was Cora, impersonating Blue OR if there was magic big enough to possess Blue such as taking her heart.
I think maybe Cora is impersonating Reggie. Funny how, in the one scene, we see Reggie’s eyes go all possessed like just before she confronts Emma. Maybe that’s why everyone thinks Reggie is guilty of murder. Maybe they all witness Cora, impersonating Reggie, murder Archie (presuming it’s Archie of course.
Back to Gepetto. He betrayed them all once with forcing Blue to allow Pino to go. I can see him doing it again. He was, after all, part of the council sitting at the round table. So he’s somewhat important when it comes to operations.
