Good points, all around 🙂
I would like to add also-
Even though MM and David were their cursed selves in SB, their True Love still came through. They kissed many times, but the curse remained.
Emma kissed Graham. Was it True Love? Potential True Love? Because he started to remember when he kissed her, yet the curse remained.
But the Dark Curse had to be broken by Emma the Saviour. She had to kiss Henry inparticular.
Because that was written into the Dark Curse.
So, I’m thinking something similar about the Dark One Curse that would prevent or stall TLK from breaking it.
TLK only gets you so far…depending on how powerful the curse is, maybe?
