Frozen 3 the possibility of an actual fifth spirit before Elsa.

So despite current status trope, let’s just say hypothetically Elsa did have some human with magic before her that is the fifth spirit. but reasons we don’t see it 35 years ago is most likely hiding, and frozen 3 can show the past from another different perspective angle. and Iduna’s saving agnarr resulting spirits gifting Elsa with powers, might not actually be a cosmic chance as it seems. I’ll explain more of my theory once we get more information next month.
