Facts of Frozen Fiction

We know a lot of things about Frozen based on what we see and hear when we watch the movie. However, not every little detail about characters and other things are revealed only in the movie. Before and since the film’s release, Jennifer Lee has revealed and confirmed some information about things that many of us don’t know entirely and want to know. For example, the film only implies that Kristoff was an orphan when he was adopted by the trolls, but Jennifer confirmed it on Twitter twice:

Another popular question I have heard before is the ages of each of the characters. I have found out the ages of Anna and Elsa from different books and excerpts of the script itself, with the latter being the same for Kristoff, but here are Jennifer’s confirmation of the ages:

And I confirm the ages myself, including that of Hans, in this analysis. Furthermore, Jennifer has confirmed that Anna’s birthday is indeed on the summer solstice, while Elsa was born on the winter solstice:

I had also heard by other users that Hans had created the shackles Elsa wears later in the dungeon. While I previously explained my insight about them, here is Jennifer’s confirmation about them:

Then there seems to be speculation about whether or not Kristoff knows that Anna was healed by the trolls before. I wrote an analysis with my explanations, and here is what Jennifer has said:

I also previously wrote a post about the chess set seen during Anna’s scenes in the library. It appeared to me that the white queen piece was symbolic of the upcoming figurative and literal fall of Elsa, and Jennifer has said it means just that:

And finally, Jennifer has said that Hans asked around about Elsa before he decided to go after Anna. Although it contradicts my headcanon a bit, I think what she says makes sense, too:
