So, nobody knows her, or remembers when she came? Obviously Roland knows her, as does Regina, since Roland says Regina lets him buy ice cream.
What if their only memories of her are recent ones because she’s lived under a spell. Her spell was bound by a witch. A living witch (referring to Zelena). But when the witch died, the spell was broken.
Pretty sure that’s what it said in the season 4 trailer but I don’t know if that refers to Elsa, Sarah Fisher, or a character from a past season.
