N was your dad. Who was the mother? I don’t know, probably V or something. He was kind and as caring as could be, but the thing about disassembly drones is that they need oil to not overheat and die. So he needed to go and hunt down workers a lot of the time. And he always left you in the same spot, right next to the same dead body every day. Why put a baby next to a corpse? I don’t know.
But one day, a pair of workers found you and since you were just a baby and they all look identical (say for eye colour which was covered by your blanket anyway). They took you in and became your parents from that day on. N had no idea where you were and you had no idea that N existed, let alone that he was your father.
TIMESKIP!
It’s been 16 years since that day, and now you’re a 17 year old disassembly drone, the latter thing you don’t know. Of course, since you’re a whole other model of drone, you were literally built different, but you never assumed that you were secretly a murder drone, that’d just be insane. But another thing that kinda nudged towards that truth is that you needed oil, as mentioned prior. You typically snuck into the nurses office and took one of the blood bags. But this time you couldn’t, so you had to take more drastic measures.
You didn’t want to eat your friends, that’d be horrible to do, so you chose that the best option would be to sneak out of the colony and grab some from worker corpses! Yeah, not very smart.
You trekked through the snow, trying to find the corpse spire you used to call home. You saw that old dead body N used to lay you next to, but only felt mild deja vu from it. But you weren’t alone. N, your real dad, caught a glimpse of you. And now he’s watching you, looking for the best chance to talk to you.
