Why everyone is hating on Robin so much…he’s between a rock and a hard place- what do you think he should have done? Not said anything to Regina at all? Dumped his wife? Really? I don’t think either of those sound any better. He is trying his best to be honorable. He can’t just ignore the situation- it involves him. We’ll see where it goes from here.
My issue is that Robin’s only reason for staying is “I made a vow.” Sure, honorable, but it also takes away from the epic love story that is Robin Hood and Maid Marian, as if they were just second rate to Robin and Regina and that’s just not true. We’ve had quite a bit of evidence that Robin and Marian were just as in love as our other couple. It came across as very “she’s the ol’ ball and chain so I gotta stay with her, but I’d much rather be with you.”
Rumple knows what he did was wrong. He feels bad- that’s why he went to the grave making a vow to fix it
But he’s not fixing it. Instead of trying to really fix it–tell the truth, confess, make recompense–he covers with more deception and lies. Including freezing his new wife.
