I know this is a wild crack theory but I thought it was odd how Elsa couldn’t see anything in um, ahem, (I can’t believe I’m saying this) Bo-Peep’s crook but then everyone could hear a heartbeat right as SNOW walked in the door. And where was Anna going for info?? The Enchanted Forest.
What if Princess Ava was Anna and Elsa’s Aunt. Which mean’s that Snow is Anna and Elsa’s cousin. Hence the reason she could hear a heart beat as Snow got closer to the apartment?
OR
Crack theory #2 . . .
Elizabeth Mitchell is a grown up Anna who made some kind of deal with Rumple in order to try to find Elsa so that he could use Elsa’s magic to cast the curse or Anna got all messed up when he tried to teach her magic knowing that she was Elsa’s sister and assuming she was powerful enough to be taught to cast the curse to get him to Bae. But some variation that makes her become a warped grown up Anna that is a wanna-be evil version of Elsa – she aged because she wasn’t caught up in the curse.
I know they are both far fetched but . . . EVIL WARLORD BO-BEEP. If that can make it past editing, both of my theories are viable contenders.
