Good Grief

Also the further parallels between Mikasa and Ymir Fritz because Mikasa lost her innocence the day her parents were killed and she was around the same age too. All three involve the death of loved ones (probably parents, but it's unclear with Ymir) and coming into contact with unknown powers (maybe Ackerman stuff I guess).

Also also... Mikasa being able to find a family only to lose it again and desperately clinging to Eren, meanwhile there's Ymir's situation where she was forced into a "family" (I use the term loosely).

Then Mikasa DOES manage to start her own family WILLINGLY while never losing sight of who she is as a person AND maintaining her love for Eren.

Mikasa showed Ymir that love is possible despite countless hardships and that there's still beauty in the world. Ymir's suffering allowed Mikasa to experience that love.

Mikasa's partner/husband is Jean. She spends a few years mourning Eren and Jean is always there supporting her. They end up getting together at some point and having kids.

Jeankasa's first-born kid, regardless of gender, is named Eren.

Everyone else (mostly) has a kid named Eren too.

Mikasa tries to distance herself from politics but always ends up getting roped into disputes. She'd rather just be a housewife.

Jean is the next leader of the Survey Corps but after a coup he gets kicked out.

Falbi are the first couple to have a kid and it's unexpected. Falco doesn't really handle it well.

Falco has a job related to peace talks and Gabi uhhhh... Gabi probably sticks to military stuff.

Levi marries a woman he meets in Marley who's a friend of Onyankopon's. Initially he's very against the idea of having kids, but his wife points out that it would be a huge fuck you to Zeke, and that (eventually) convinces him to be a dad. Everyone is shocked when they find out.

Connie has a thing with Nicolo. They hook up after Connie starts working at Nicolo's restaurant.

Annie and Armin get together, rush into marriage, have an unexpected kid and things proceed to go tits up. Armin is very mentally unstable for most of the rest of his life.

Annie works as a martial arts instructor and passes on the teachings of her dad. Armin becomes a marine biologist after he steps down as the Survey Corps commander and passes the job on to Jean.

Reiner remains single because he doesn't think he's worthy of someone else's affection. (And his crush is taken.) He's a nurse? Idk I like nurse Reiner.

Pieck never marries. She spends her days working as an archivist for Marley.

Yelena survived and was arrested and sent to jail for war crimes. While in jail, she discovers she's pregnant, escapes and runs off to a far-away country. Her kid is either Eren's or Zeke's (I haven't decided which lol) and she keeps them hidden.

The kid walking up to Eren's tree at the very end of the manga is Mikasa's descendant and they're looking for Eren so they can awaken the powers of the Founding Titan and revive him.

Falco and Gabi eventually reclaim the Survey Corps from the Yeagerists and end up being in control of most of Paradis's military.

Onyankopon is a hairstylist? Also I see him getting married but maybe not having kids.

Historia's husband is killed during another uprising attempt but Historia and her daughter are unharmed.

A few decades after his death, Eren becomes a meme.

Eventually the idea of titans becomes a conspiracy theory and many people don't think they ever actually existed (or at least not in the way they did in canon).

Paradis eventually becomes completely uninhabitable -- as in the entire island, not just the hill. However, a handful of people escape to the underground and reside there. The underground is accessible through Eren's tree, and many inhabitants are related to the main/secondary characters.

Mikasa's descendant discovers the underground civilisation and gets to know the people living there.

Eren is chilling in paths in place of Ymir Fritz and gets a surprise when someone who looks kinda sorta like Mikasa shows up (don't ask me how they're able to use paths, maybe it's the direct contact with the Founder).

Maybe eventually, once it's destroyed, Paradis is treated as though it never existed and is erased from the history books. Similarly to Paradis residents being brainwashed into thinking the rest of the world is gone.

Mikasa passes on the Azumabito mark to her kids and they pass it on to theirs.

Mikasa's descendant never visited Paradis because it was destroyed before they were born, but they would always read their (great?) grandmother's diaries and letters and wished to go one day.
