~•°☆Frozen Headcanon x6☆°•~
+ Ryder and Olaf +
So, for our first headcanon of the day☆°•~
I think Ryder (at least for a while) would not like Olaf. Olaf (despite how much I love him) is a creepy sentient snow goblin with a funny voice that can tear itself apart at will. Plus the Northuldra have a... to put it lightly, turbulent relationship with magical creatures (meaning he'd naturally be less comfortable with Olaf, compared to the Arendellians who have a pretty positive relationship with magic).
I think this would be really fitting because Olaf's F2 arc was all about getting older, maturity, change etc. And an important part of growing up is realizing that some people just don't like you and learning how to come to terms with that.
Ryder would try to be nice to him (for Kristoff ♡), but his discomfort would be obvious~~
Ryder trying to be nice to Olaf: uh... hi?
Olaf, in a singsongy happy-go-lucky voice: You know one day we are all going to die?
Ryder, thinking this is a threat: I'm sorry
+ Ryder and Kristoff +
- Ryder is a reindeer expert and Kristoff (and Sven) are excited to learn! Since Ryder grew up in a tribe that focused mostly on reindeer herding (while Kristoff seemed to work more or less alone with Sven) I think he'd have way more reindeer related knowledge than Kristoff. Kinda like the difference between having a cat and owning a cat sanctuary. We know that Kristoff and Ryder hit it off real quick in F2, so I'm sure he'd be happy to teach Krisoff all about reindeer.
Ex: The reindeer, leapfrog whatever the Northuldra were doing in the prologue♡
Or in HTTYD (for another fantasy example) with Valka (who lived alone with thousands of dragons) vs Hiccup who only had a connection with Toothless and a few other dragons.
I think this gif best shows what I'm talking about since:
A) dog people love getting licked by dogs. Sven acts like a dog, sticks his tongue out a lot, and IRL reindeer stick their tongue out a lot
B) Ryder and Kristoff are already lowkey crackheads for speaking for the reindeer lol. So this is on brand.
~°•☆Ok I'm done thanks☆•°~
