You are the last human on Earth. You are an underground banker. And while you were walking through what was once a city, you find J deactivated and its head disconnected from its body. I'm going to take it to the banker to fix it. 21 days pass and after a lot of work, J reactivates. When J sees you, she thinks you are a Worker Drone

J: "Oh, I would appreciate it, but it's a shame that... you are one of them" J would kill you, but that's when she realizes that you are a human and a protocol in the back of her mind is reactivated. The protocol is to take care of and protect humans

J: "Okay, that's... weird... but okay... do you have a name or something like that?" It's obvious that J is getting used to the protocol
