Okay, so let’s talk about the immortals and the serum because I swear something is not adding up, or rather it's adding up too well lmao.
The recent shift in Anhea's behavior isn’t just a coincidence, and I’m willing to bet my wheel of fortune spin that the serum she gets injected routinely has something to do with it. First of all, immortals were always described as distant and detached from the mundane world, almost like they were operating on an entirely different emotional frequency. Anhea, who was always pragmatic and painfully logical in her mannerisms and actions, she who always kept her distance is now shielding the other girls with her wings like it’s instinct, grieving for kira, and even offering to go inspect unexplored places first. That’s not just a change in attitude, but something deeper, something internal. Even Pileon, who didn't take the serum as far as we know (correct me if I'm wrong), looked surprised at her behavioral change.
And here’s where my theory about the serum kicks in.
We already know that Adam base, aka Donovan, was running experiments on immortals before the collapse of the base. The squad found documents that hinted at it, and honestly, it makes too much sense. I'm not a scientist by any means, but if humans were developing medicine (or any other chemical concoction) specifically for immortals, wouldn’t they need some kind of common biological link to make it work? So, what if the serum is a mix of human and immortal DNA? Or maybe they infused immortal blood or dna with human ones... idk, but certainly something of the sort. This fusion would basically act as a genetic bridge that, when injected into an immortal, might not just heal them, but it could also be changing them emotionally speaking. Softening whatever kept them so detached and making them more human, or akin to experience and/or understand human emotion.
Hell, even Lane found Cain's behavior strange, nicer and chattier, just after he took the serum to heal the wound he suffered when he took that bullet for Anhea in the boat attack. He's now smiling more, acknowledging past conflicts, and even reaching out first? He even found the courage to confess that he and Lane knew each other.
Think about it: Cain and Anhea aren’t just suddenly nicer. They’re feeling things more openly: protectiveness, camaraderie and friendship, even self-sacrifice, things that seemed rare before. And what if that’s not a side effect but the intended one? If the goal was to create something that helps immortals heal, maybe that “healing” extends beyond the physical. Maybe the experiments' goal was to undo whatever made them so emotionally distant in the first place in order to tame them; to be able to inflict fear in them so it becomes easier for the government/military to make them submit and become valuable assets.
But then that raises the question: If Cain and Anhea are just now showing these changes, does that mean the effects of the serum build over time? Imagine how much time has passed since the beginning of the experiments... There could be dozens of immortals out there experiencing the same changes. If this theory is right, then we’re looking at something way bigger than just medicine. We’re looking at the weaponization of immortals. Because if this serum is making them more human… what happens if they keep taking it? How much of their immortality is actually tied to that detachment? And at what point do they stop being what they are? And if the military or the government actually manage to finish the experiment and really create an army of immortals... they're so cooked lol
