I’ve investigated further into these individuals and as they all seem to follow a certain pattern in expressing emotions and even, but barely noticeable, motions – I conclude they are spydroids with unknown origin.
By accessing and reviewing low level security recordings of their whereabouts and interactions with TSN personnel, I discovered they all follow either one of so far two kinds of (wasmannian?) mimicry to resemble human.
Flashheart, don’t be too hard on yourself – but don’t forget to shower after visiting the reverse flushing compartment of TSN Hunter.
