Things used to be so…simple. Or at least, it used to feel that way. Kill the Titans or they’ll eat you; for the sake of those you love, or duty, or plain old revenge. Not only are things not that simple anymore…they never really were. The further behind the wall you get, the more complicated things seem to get, but at least there are two simple truths to grasp: one, Historia Reiss is the heir to the throne, and two, not all humans are on the same side; not by a long shot.
For whatever reason the Titans are not an imminent threat to mankind’s survival, so now their internal divisions are laid bare before us. Chief among those divisions are the Scouts vs. the Military Police, and Levi and his squad find themselves outnumbered, out-maneuvered, and generally out-matched by the MP contingent led by Kenny, the man who raised Levi and still thinks he’s a kid that can be jerked around.
It takes every last ounce of grit and resourcefulness, but Levi just manages to get one over on Kenny and his cohorts, in an elaborate but very slick sequence involving a showdown inside and outside of a saloon (apropos considering Kenny’s cowboy-western style).
Levi figures out pretty quick that it’s time to start killing his fellow humans lest he get killed, but other than Mikasa, the other squad-mates have trouble adjusting to the very abrupt change in mission. Jean almost pays dearly when he hesitates to kill the woman at the reins of the wagon carrying an unconscious Eren and Historia.
But the woman hesitates too—whether she personally knew Jean (sister?) or just noticed how young and scared Jean looked—but Mikasa is a beat too late to kill her. Instead, it’s Armin who carries out Levi’s order to kill, and just like that, he’s a changed man.
He later laments that they’re no longer “good people”, let alone “good guys”, as they’re no longer taking the lives of monsters that would otherwise eat them and others. Now they’re fighting for a faction of humans, not all humans, and are forced to kill to preserve the way of thinking they deem to be more “right”.
While it’s hard to see what choice they have, I still acknowledge Armin’s lament, and share in it. These kids wanted to serve their people, but now that Eren and Historia are being hunted not by Titans but other people, they must do things they never thought they’d ever consider doing. Perhaps even worse: they quickly learn they’re pretty good at it.
By the end of the episode, Levi and Hange have resided over murders, kidnapping, and torture…but also become reasonably certain that Historia is now in the hands of Rob Reiss, of the Reiss family, who are the true heirs to the throne. But the Trost merchant who played both sides and helped them capture Sannes is later killed by Kenny, leaving his company and the futures of the people who depended on its business in question.
Sannes too proves a true patriot, unblinkingly believing that the horrible things he and his men did throughout the years were absolutely necessary for the survival of the kingdom and preservation of peace within the walls. From his perspective, what he did was as important (or moreso) than the Scouts killing Titans.
In that regard, Levi, Hange, and those under their command have joined the ranks of Sannes and the Military Police: dirtying their hands and eroding their souls for what they believe to be the right reasons. To survive against Kenny and the royals presently in power (who have no intention of giving that power up willingly), and to rescue Eren and Historia, they’ll have to be as ruthless as the Titans that invaded their city and ate their friends and family.
