Slurpeez, stop trying to make “fetch” happen. It’s not going to happen.
Anyway I sent this theory to the feedback email:
Emma is Helga reincarnated.
Snow was born during a harsh winter, right? Much like Winter Storm Elsa, AKA the Polar Vortex. Now, a common theory is that this winter was caused by Ingrid. What if this storm is what got Ingrid trapped? What if she killed Helga the same way Elsa nearly killed Ana [sic] (and Ingrid, as far as I’m concerned, killed Hans)?
Anyway, Helga could have shattered (like the mirror) and her pieces could have ben blown by the storm as far as Misthaven. Snow would then have been born during this storm and somehow “bonded” with the pieces of Helga.
