I can spot NPCs now, not all the time but beginning to see the warning signs.

One warning sign of an NPC is that they'll reply endlessly with "cope" over and over again, as if someone spilled water on their mainframe and now it messed up their algorithm or the part capable of speech so they have no choice but to be a parrot. It's horrible, imagine being a sentient human reduced to the husk of an NPC. You're still able to think in your own mind but for some reason another identity has over taken you, almost as if there's no free will and it's all just that you're programmed to be this way.

Horrifying.
