I agree, I don't think there's a connection between Mikasa and Kenny. Other than their last names. As for Levi and Kenny, maybe sort of like an unofficial adoption. Or maybe they had a similar relationship to Haku and Zabuza from Naruto. In simplified terms, Kenny gave Levi a purpose in life. Hopefully some light is shed on that matter in this upcoming chapter.

I feel like Ymir would come back to save Historia. But how could she know what's going on with Historia right now? How will she know where to go? And how would she have made it back within the walls without a distraction?

I sort of feel like the Reiss' interest in capturing those two would be to ensure that the walls never fall. And to ensure that the secrets of the walls never get out. For all we know Historia has some repressed memory of the Mysterious Woman telling her the secrets of the walls.

As for Captain Ackerman's connection to the Central Military police. I like the idea behind his connection in the trivia section on Kenny's page. Or possibly after killing all those people he finally got caught by the government. But they decided to give him a deal. He joins their ranks and his slate gets wiped clean while no longer being on their "hit list".
