Looking back at her brief but happy time with her brother, Mary remembers a kind and gentle boy who took care of her despite being young himself. He always held her hand, and even braided her hair. When he left, she was proud of him for finding the Place Where He Belongs, but in doing so he was taking what she deemed to be her place (by his side) away.
Mary doesn’t see any of that old Victor in the monster before her, so she does what any sister would do when pinned to the wall by her brother’s mecha-ribbons: launch her boob rockets. I’ll admit to having slightly missed the point of Juuzou’s bashfulness at the sight of Mary’s larger chest last week.
As cool as this tactic was, I still don’t know how Mary’s face and body weren’t horribly burned in the process. Regardless, she’s able to stop Victor from dissecting Juuzou until his uncontrollable final form comes out, and Juuzou is able to rip his arms off, which is key because Victor’s hands can dismantle any technology they touch (including one of the rockets).
Unable to discern whether the “real” Victor was the brother she loved or the monster before her now, the only way to keep him from hurting those she cares about is to put him down. She does so by firing Juuzou’s trigger, which blows off Victor’s head and most of his shoulders, ending the immediate threat.
After that, “Lefty” suddenly reappears, damaged but still intact. He even hooks himself up to the voice box of one of the police Extendeds so he can talk to them properly. Turns out the “real” Victor was never the demented puppet they tangled with.
Victor’s own body has been taken over by the dual parallel sub-brain he’d developed, which has a personality and will all their own. Destroying the puppet this “Shadow” Victor was controlling caused enough of a shock to allow “real” Victor to surface and open a dialogue.
Victor tells Juuzou and Mary how as an engineer he was committed to ending the loss of life and limb on the battlefield through the development of ever more advanced Extendeds, working towards fully remote models that would eliminate the need for flesh-and-blood boots on the ground entirely. Of course, it wasn’t until he tested out one such model on the front lines that he realized that what he was doing wasn’t saving anyone, simply upping the volume and efficiency of the carnage.
The shock of seeing this created an opening for the sub-brain to take over his real body. The thought he had at the moment of transfer—that all Extended should be destroyed—became Shadow Victor’s primary driving force, which led him to join Spitzbergen. Before Shadow Victor regains control, Victor begs Juuzou and Mary to find his real body and remove the sub-brain. Only then will the shadow’s reign of terror end.
While I’m glad the circumstances surrounding Mary’s brother aren’t as simple as “boy turned evil”, this episode got fairly bogged down in Victor’s exposition, which killed the momentum of present events. As a practical matter, having to sit and listen to him also meant Juuzou and Mary couldn’t escape to some safer location.
They really should have tried to do this, as Mr. Law Upholder Avi Cobo walks right up to them, shoots Juuzou down, and holds his gun to Mary’s head, telling her she’s not doing anything with Victor’s real body. He’s going to take it into custody “in accordance with the law.” Mary in mortal danger to end two straight episodes? C’mon, NGL.
