As I’m a big believer that Rumple is dying* in the finale I would say it’s a final goodbye. He was essentially wishing them Godspeed on their future.
It does hearken back to when he first gave Belle up in “Skin Deep.” He freed her to go to the village after her speech about love and bravery. This was probably his second selfless act. Yes, he let her go other times but he, as well as the audience, always knew it wasn’t forever. This had a forever feel to it.
I am in a position where I’m a ScarletQueen and a Rumbelle shipper. I came to love Will and his struggles on Wonderland. He gave the most wonderful speech about love to Ana and it hurts that we have no idea what happened to her. But I can see if Ana and Rumple were both dead how ScarletBeauty could be a good thing. They’re both sweet people who have had true loves plagued by darkness. But like most other things, they’ve mess up this ship business royally and I just don’t know what to feel.
*I think Rumple is dying but Bobby may stay on for the show for flashbacks, which would cut back his screentime.
