Doctor Gibbons reports to his superior that the next round of test subjects all survived and are healthy. That, so far, their hormonal cascade theory is proving to be plausible. The commander is pleased, and requests he start yet another round of subjects the next day, to increase the sample size. That she has pre-screened military candidates flying in that evening.
He tries to supply an update on the male enhancement program, but she's not interested in hearing it. She asks if he has any leads on encouraging the same growth process in men. He doesn't. She tells him that eventually he'll work on that, but for now, focus on the female testing.
Kim and Arnold have some private time together, where we get to see signs of Arnold wishing Kim was more like TJ. Kim makes reference to him getting to see more superhuman women around, because of her breakthrough theory.
We get to see the scene the next morning, as Doctor Gibbons addresses the room of test subjects. Arnold is present to do some routine blood work on them. The doctor explains the procedure, that they'll be using batches of six. The women are losing decorum, and giggling a little. One of them politely asks if this is a joke. He brings in TJ, who is 8' tall and has incredible muscle definition. They are all shocked. After there are no more questions, Dr Gibbons and TJ leave the room, leaving Arnold to administer his blood draws. He can hear them murmuring with anticipation about the procedure.
A week later, the female barrack is a buzz with a dozen 7' tall post-procedure soldiers. TJ still towers above them, and has been asked to command the platoon. She addresses them about their day, and reprimands some of them for acting less than appropriate to male superior officers in public - while suggesting that what consenting adults do in private is their own business. She also points out that fraternizing with non-military personnel is less complicated.
Two of the new soldiers corner Arnold during a lab tech session, and proposition him. When he tries to politely refuse them, they up their game, flirting and trying to explain how satisfying it could be for him. When he explains that he has a girlfriend, they just keep pushing, explaining that they aren't just any girls. That their size and strength comes with certain advantages. (listing off some) Finally he confesses that his g/f is Kim, one of the non-military test subjects. It takes them a minute to get it, and when they do, they finally let up, though they comment that it makes them "want him even more" because he knows what he's doing. They ask him if he knows of any non-military eligible men he could send their way, since they can't find men very easily when they can't leave the base.
We see Kim and Arnold meet at the end of the day. Kim is now 7'6", and extremely toned and defined. Arnold guiltily confesses about the proposition, which just makes her curious. She asks all about what they did, exactly. She patronizes him, about how hard it must be to have beautiful super human women throwing themselves at him. He tries to defend himself. She makes reference to needing to "stay ahead of her competition", and starts undressing for him, encouraging him to touch her. Their session is a mix of him worshipping her, and her pampering him for it.
We see Doctor Gibbons, surprised that the last six subjects are late for their treatment session. He asks Arnold if he knows anything about it. He doesn't. Then his commanding officer shows up with two other female officers, and he salutes in attention. He explains that today is the treatment session for the last set of recruits, but they haven't shown up, and he was just about to find out why. She explains that won't be necessary. She's moved their treatment to the next day. He'll be doing a treatment today, but not on the recruits. My superiors have decided it's time to bring some officers into the study, so you'll be treating the three of us.
He tries to object, that this is "highly irregular". This is a scientific research study. They still have yet to understand the full effects of the procedure. There could be unforeseen consequences, negative consequences.
She cuts him off, "we're well aware of this, doctor Gibbons. Yet we need officers who can maintain authority over our new soldiers. We will be undergoing the procedure. Today."
We get to see a 'streamlined' version of the procedure occur on them. Including them getting into patient gowns. Resulting in growth to about 6'10". His commanding officer monologues about how impressed she is. That she was initially concerned about his research, but that it's exceeded her every expectation. She asks if they have established a final growth limit yet - how tall will she get?
He explains that TJ is 8' tall and hasn't stopped growing, but that the cellular lab studies they've done suggest she's near the growth limit.
She's pleased, "something to look forward to". Then she asks him for something to wear and to show them to the biometrics lab.
In the biometrics lab, the commander maintains control of the conversation, confirming what she's supposed to expect about their weight and strength. One by one, the girls are put through their paces, with the commander commenting that it's "one thing to read about the results, but something else entirely to experience them"
