(huge spoilers for episode 2)
At the start of the episode we get this creepy scene in a mansion, in that scene we see four worker drones, three of which resemble the ones we know, n, j, and v
However a fourth one is revealed at the end of it
So I think that at some point they were upgraded to murder drones.
Also chainsaw hands is canon, not my artwork but clearly glitch saw it and thought it was funny
Everyone reading this who saw episode 2 already is probably just thinking "no sh*t Sherlock"
