"He was a lot of things to me" "The only conclusion was love"
I think that in that moment where Snow tells Emma that it’s time for her to leave them again, Emma, finally, understands why and how it was unavoidable that they had to send her through by herself and hope that she would find them again and have her best chance. The feels!
I was already a wreck by this point but when Snow kissed her forehead and Emma’s face when Snow removed her hands
GOD. I lost it. Utterly. Just sobbed and sobbed. And yes, Emma now know that sometimes it’s unavoidable. You have to do what is right even if it’s the wrong thing.
