Okay, so, I remember that I really love Rose of the Guardians. And I'm a fanfic writer who has seen enough edits of angst that it's infected me a little. Plus I've read a lot of fluffy fanfics that are amazing, and that countered the angst train quite a bit.
BUT
I read a fanfic or, maybe it was I had seen a post, or maybe it was an edit, but someone mentioned that Jack (remembering it was in a fanfic from Sandy's POV and maybe also an edit) died as a child before becoming Jack Frost.
It's pointed out that Jack Frost is on the Naughty List, which was mentioned to be just for kids. The lists are for kids. And Jack Frost is on one of the Lists. Making it glaringly obvious that Jack is a kid. I estimate him to be like, 14-16 years old. Give or take.
I really have no other point to this post other than the fact it's been infecting me with the feels.
