I am rewatching Season Four A, and I have a doubt. I think I might have missed something, but when does Elsa regain the memories Ingrid had taken from her? Because at one point she "realizes" that Anna could only have put her in the urn if she was under the shattered sight spell (which was only an assumption she made), and the next episode she says "Anna didn't really mean what she told me, it was the spell." or something like that... But when did it turn from being an assumption to being the actual memories?
