yumimika 🤔. How do you think the dynamics between them would be?
Thanks for the ask anon! I wanna apologize in advance cuz I'm gonna go on a lot of tangents here (that are borderline fanfiction) because Ymir and Mikasa are my 2 favourite characters in the series and I just love the dynamic I've built in my head for them.
If I had to device a plot to get these two together it would have to be with something completely separate from their relationship/feelings from Eren and Historia. I just feel like it would be a trend if this ship had a bit more attention and that brings so much bad taste in my mouth I don't even want to think about it.
To elaborate on that, I would love to have them as secret friends. We all know Ymir has a bitchy exterior but a big softie interior and Mikasa is all tough and stoic on the outside but soft and feminine on the inside.
I just think that with Ymir being incredibly nosy and perceptive (she reads people very well fairly easily), it's hard to believe she hasn't thought of Mikasa and analyzed her at one point in training camp. I believe she has multiple times and maybe even confronted her about whatever she sees in her (be it her feelings/devotion for Eren, her soft side, or something else).
I think Ymir's tendency to be annoyingly nosy could bring her closer to Mikasa. Just to be clear, I'm talking possibilities they couldve had at bonding during their trainee years. Since at that time it seems as though Eren and Armin spent more time with each other than with Mikasa (girls and boys cabins were separate), Mikasa would've had to bond with other girls and Eren may have even pushed her to. Relatively speaking, it would sound like she'd get along with Sasha the best and would probably spend most of her time with her if not with Eren and Armin. And I think that's the case.
BUT, I think during uneventful, mundane days, girls separated from the boys, Krista* hanging out with other girls and Ymir and Mikasa finding themselves alone with Ymir bored, there would be time for them to get to know each other in secret. A time for Ymir to try to pry Mikasa's deepest darkest secrets, to get her to snap, to make her vulnerable so when the time comes, she can use it against her (Ymir is super cunning and smart much like Armin).
Mikasa is also smart though, so she'll most likely be unaffected by whatever Ymir puts on to her. And maybe the mundane will bring Ymir to the realization that penetrating through Mikasa's walls is near impossible so she'll give up eventually. But instead of leaving her alone I have this headcanon that Ymir will try to get a stab at a genuine connection with Mikasa, asking her about her interests (maybe knitting??) sharing their opinions, etc and it'll be like a shared secret between them on a mundane day. And maybe they're both insomniac and late night walks would calm them down and they just so happen to bump into each other at various points in the middle of their late night walks and decide to walk together, sharing small discussions and not saying goodnight after they get back into the cabin.
I was also thinking that since Eren spent like 95% of one on one combat trainings with Reiner and Annie, maybe Ymir gets "roped" into sparring against Mikasa and Mikasa is more than happy to indulge herself in giving Ymir a good beating (after so many annoying ass shit Ymir has tried to pull on her).
So, as a bit of a tldr: I think their dynamic would be a secret bond, a secret friendship/softness with each other, sharing thoughts/opinions and maybe even secrets only privy to themselves and each other.
I also think this would give the scene with Mikasa telling Historia (during Reiner, Bert, Ymir's kidnap attempt on Eren and Historia) that she doesn't have space to care about other people any more, much more depth to it. And the part in season 1 where Ymir asked about Mikasa, if she's okay or not,, not sure if that was on the manga but I'm pretty certain it was on the anime.
