I understand Rumple’s motivation, I do. He does have the tendency to lash out to people whom he feels wronged him but he lied to Belle again.
And this is bigger than a lie; he mislead her to believe that he trusted her to hold onto his dagger and not use it. He really did not need to do that. He could have taken it back.
I feel like this might be the last of rumbelle? How do you come back from misleading someone on purpose to get some revenge, even if the revenge was semi-justified?
Chances are, Zelena’s murder will be found out next episode. David’s still sheriff even though he’s on paternity leave. It’s going to come out and Belle will find out and she’ll know Rumple was responsible. I would be very disappointed if Belle ends up never knowing because honestly, that would be worse because it would be a marriage built on lies and deception as opposed to a true happy place.
