Adam said Blue didn’t have her memories, and yeah, that squished a lot of theories. The only indication of Rumple’s origin story being in the book is the fact that Bae IS in the book. Of course, I wonder when Rumple found out about the book; I assume he might know about it at this point, but did he know during the curse? (Probably. Man knows everything.)
I know they said that but that doesn’t mean she didn’t required them back like Rumple did some how. Plus the BF being clever with her reply to Gold on why August was there in town and since the BF stated that she had to get prepared for the curse could be doing the same thing Rumble did.
