64 for the Zeldas. If there are funny Link answers, feel free to add those. (But save this ask for later, I know you have stuff to do tomorrow 😳)
How good or bad is their sense of direction?
Boots' Zelda: I think pretty average? She's alright, she can manage, but she's not like spectacular or super speedy. She's good at keeping a level head though, so even if she got lost, she'd make a plan and go for it without panicking. Boots is kind of average too, but has a tendency to get more frustrated when he gets turned around, which just kinda makes him even worse lol
Crown: While her Link has a decent sense of direction (he might veer a little bit this way or that but ultimately head in the right direction), she's better at reading maps. And I'm not even talking about text as much as just like understanding it haha. He understands the basics - the cardinal directions and knowing which way he should head to get to whatever location, but the distance and stuff means nothing to him. He just knows Go That Direction and we'll get there eventually probably. Crown, on the other hand, struggles a bit more when it comes to the physical part of navigation, but the mapping part is easier. She does have a bit better memory for navigating dungeons though, actually. He gets a wee bit more confused when there's a lot of rooms set up in a complicated way, and looking at a map doesn't help him as much compared to Crown.
Love: It doesn't come naturally, but if she focuses, she's actually pretty good at remembering where she has and hasn't been, keeping track of landmarks, and so on. She needs to learn the actual navigation part beyond that, but once her Link teaches her, she's set. She's actually better than him at recognizing little details of similar looking rooms and remembering where they have and haven't been. But when it comes to bigger and broader navigation, long distances, he's better.
Queen: She memorizes places very quickly, but she's not accustomed to being in charge of actually getting places. She could absolutely get back to the place she came from though just because she'd remember the route taken and work it back. With a bit of learning, I think she'd be fine. Jester is surprisingly good at it. His brain is going a lot more than it might seem on the surface, and he's very spatially aware. He's kind of had to be his entire life.
Forest's Zelda: Unlike the previous one, I do have an answer for this one. (I wonder... If I should call her Castle or something... He's a child of the forest, and she's a child of the castle? Idk, I'll think on it. Opinions and suggestions always welcome for Zelda nicknames!) She doesn't have a very good sense of direction because she's never needed to exercise it... While her Link is the opposite. He might not know where he's going outside of the woods bcuz most of Hyrule is unfamiliar to him, but he can use the sun and stuff to navigate. I think she'll be a bit better by the end of their adventure since she'll have learned from Link though!
Bonus, not a Zelda, but... Sonya: I think she's pretty good! It might take her a moment to figure it out, but she could do it and it wouldn't take her ages. In a place where everything looks super similar, it might take her longer, but she'd manage. Better than her Link in an area like that, actually. He's just fine if he can see the sun, or if things look different across the board, though.
Wound up answering for (most of) their Links too just as a compare and contrast lol
And since I did that, Poncho is fantastic. Zero issue navigating whatsoever.
