As Rob Reiss prepares to instruct Historia to inject a serum that will transform her into a Titan so she can eat Eren, Hange and Levi’s team enters the cavern, sporting some unconventional tactics in order to level the playing field against Kenny and his intensively-prepared anti-personnel troops.
With a combination of surprise, gunpowder, signal flare smoke, and pure guile, Eren’s allies are able to get right on top of Kenny’s people; the hard part is having to make the decision to kill their fellow human beings for the first time.
The sequence is taut and intense, but doesn’t forget to show those tiny moments of hesitation that linger in the thoughts of Sasha, Jean, and Connie. Not surprisingly, there’s nary a shred of hesitation in either Levi or Mikasa.
Kenny himself enters the fray, and quickly finds his nephew Levi is a lot tougher than he gave him credit for, successfully wounding him in the midsection and forcing him to retreat almost as quickly as he arrives.
But his presence gives his second-in-command the opening she needs to deal a crushing blow to the Scouts: by getting the advantage over Hange Zoe and seriously wounding her. If she isn’t able to get back up, that’s a huge blow for the good guys (even if it’s been demonstrated that neither Hange nor anyone else is 100% good or bad here).
This season of Titan continues to be generous with its answers regarding what the heck is up with this world, filling in a few more of the many blanks that have lingered for nearly four dozen episodes. Rob is the source of more world history wisdom. Turns out most of society, due to the mind control of the Reiss Titans, don’t recall any history beyond 100 years…no doubt since an ignorance populace is easier to control.
The Founding Reiss Titan used its power to built the Walls that protect humanity, but also passed on all the knowledge that proceeded the boundaries of the rest of mankind; how the world as they know it was formed and how to preserve it. That is now Historia’s repsonsibility; she has to eat Eren in order to inherit Freda’s memories as well as her powers.
When an eavesdropping Kenny hears that only someone with the blood of the Reiss’ can inherit the full power and memories of their predecessor (meaning if he took the serum and ate Eren, it would be meaningless) he’s pissed.
More than having planned to betray Rob, he knew Rob knew he’d betray him one day, and even counted on it, but not until it was all but too late to do anything about it. Rob releases Kenny from his service, and Kenny in turn decides to make things interesting by removing Eren’s gag and cutting him so he’ll transform and give Historia a fight.
That would have likely been something quite awesome to behold…but something perhaps more interesting happens instead: Eren doesn’t transform. He doesn’t want to; he wants to die. He sees himself as the cause of all of the trouble they’ve been in up to this point, and more importantly, all of the people who died, who he lists in roughly the order in which they died.
With both Rob and Eren begging her to inject herself with the transformation serum and eat Eren, Historia seems stuck between a rock and a hard place…but there’s still the matter of what she, an individual, wants to do, even if her duty seems clear, while her victim is ready to die for the sake of humanity and correcting perceived wrongs, both his and those of his father.
But then she remembers Ymir, telling her whether she’s simply trying to do something “nice” (i.e. what she thinks everyone expects of her). She also rememebers that time on top of that castle, when Ymir, before transforming, tells her that all she wants is for Historia to live a life she’s proud of.
‘Tori can’t do that if she injects herself. She can’t do that if she eats Eren. She can’t do that if she exterminates the Titans. Rob calling what she’s becoming to be something akin to godhood is the last straw. She slaps the syringe out of Rob’s hands and it shatters on the ground.
Historia decides to free Eren, because she likes him a heck of a lot more than she likes the rest of humanity. As far as she’s concerned, they can all get wiped out by Titans—hell, she’ll even lend a hand, declaring herself both “humanity’s biggest enemy” and “the worst girl who ever lived”…neither of which are true. Humanity’s true worst enemy? Itself. Historia Reiss? More badass than bad.
Unfortunately, Historia is also her own worst enemy, as she breaks the syringe but then rushes to free Eren, leaving the puddle of
MacGuffin transformation serum completely unprotected, ready to be lapped up by anyone. And not just anyone laps it up; Rob does, not long after telling Tori in no uncertain terms that he should never be the one to transform. We didn’t learn the reason why, but I imagine we will, very soon.
