In light of her brother’s apparent return, Mary tells Juuzou more about her and Victor’s past as orphans. They were taken in by an engineer named Emmet, but when Victor got interested in Extended tech Emmet objected. Since Emmet had become a violent drunk, Victor killed him before he could hurt Mary and fled.
Mary only ever got one letter back from Victor saying he’d joined the military, but what she doesn’t know is that he became Juuzou’s primary engineer during the war. Juuzou assumed Victor had died, but considers the man’s dying wish to be his first request as a resolver: Protect Mary.
What Juuzou doesn’t understand is why Victor joined Spitzbergen, and why he’s getting Mary involved in dangerous shit when he told him to protect her. Their talk is interrupted by the pair of Spitzbergen enforcers, but despite the larger of the two describing his anti-Extended armor in great detail, Juuzou still manages to blast it to pieces anyway, safe in the knowledge he didn’t have to hold back.
Juuzou is actually find giving Spitzbergen the data, as long as the hostages are returned safe and sound, but that willingness doesn’t imply he won’t punch somebody for daring to kidnap members of his “family”. He and Mary head for the Kyusei Pit.
Meanwhile, Tetsuro isn’t really treated like a hostage, but allowed to walk free without restraint. He’s brough before a high-ranking member of Spitzbergen named Wachowski, a clear homage to the creators of The Matrix.
Wachowski reveals something to Tetsuro he had forgotten as part of his amnesia: he betrayed his father, left Berühren, and funded Spitzbergen. Tetsuro can’t believe any of it, but he can’t necessarily dismiss it out of hand, either.
Whether Tetsuro became aware of the plight of the downtrodden and oppressed as a result of Berühren’s greed and wished to balance the scales by helping its enemy, who can say. All we do know is that Victor Steinberg is not a good guy anymore.
When Juuzou confronts him and asks why he’s sabotaging his request to protect Mary, Victor reveals that his main goal is to dissect and research Juuzou himself, down to his last bolt. He also knows Juuzou will never fight for himself, only to protect others.
That means in order to unleash Juuzou’s “true form”, he must put a member of Juuzou’s family—in this case Mary—in mortal danger. Victor’s claims to be “reaping what he’s sown” by joining Spitzbergen seems to be in conflict with his more scientific desires.
One thing’s for sure: Juuzou isn’t going to let Victor hurt Mary. It’s fitting that’s their names, since Victor is acting very much like a twisted Dr. Frankenstein, while Mary is likely named after Frankenstein’s author Mary Shelley. Famous name-borrowing aside, looks like a big bruising Juuzou-Victor fight is primed to commence.
