Hm, if Grace and Pino are filming, then it is more likely modern day SB stuff. Though I’m surprised at Grace since we won’t see Mad Hatter, unless of course, they use her to exposition in why we aren’t seeing him in OUAT WL or OUAT or something. Maybe she’ll imply he’s gone off to find her mother or something and can’t help rescue anyone.
Still we don’t know where/how Hatter got Grace do we? It is also still possible that she also was in NL (they didn’t keep Wendy, but did she say they didn’t keep girls in general, or just let her go?). He jumps around, possibly through time, so maybe Grace could have been alive way back then .
“If I had a world of my own, everything would be nonsense. Nothing would be what it is, because everything would be what it isn't. And contrary wise, what is, it wouldn't be. And what it wouldn't be, it would. You see?” -- Lewis Carroll, Alice's Adventures in Wonderland & Through the Looking-Glass
