That tech screams MK-ULTRA if used for nefarious reasons. Can work wonders for those who are paralyzed or have memory issues. Looking at the "published in research" section is very interesting. Some of the research alludes to "unlocking the human potential" such as augmented strength and maybe training the brain for telepathic or telekinetic abilities, and super memory and calculations.

What if this Motel was used to kidnap people and experiment on them. When they are done, they drop them off at the Motel all drugged up or whatever and just let them go do whatever. Whether the augmentations are left in them or not, we do not know. Why these two were armed, could just be because it's Alabama, where everyone is armed to the teeth.
