>>115043787I'll share my headcanon with you, which is actually pretty fucking dumb but bear in mind that it's been my headcanon for almost 5 years.
Autism begins:
I believed Elsa was the reincarnation of the original Snow queen, and Anna was that of the "lady who knew magic", which is a character from the book that some versions write as the "Summer Witch" (sometimes written as the Snow Queen's sister).
I believed that something had happened between the two after or near the conclusion of the Snow queen's story, a confrontation which I won't get into details here, hence why she simply vanishes from the book.
Long story short, the Snow queen died.
So when Frozen 2 happened and we reached Ahtohallan, and it's this buried ice palace in ruins, I was more than excited; Then the dress transformation occurred, all these memories were projected and Elsa's personality kind of changed, it was magical for me, it was my headcanon's moment of triumph.
tl;dr Please ignore me, I have autism
