Family reunion sort of thing. From POV of teenager/young adult.
Fight breaks out, as it does every family get together
Find great uncle (late 60’s ish), starts talking about family history
A family member started the robot wars
Uncle was on “death squad” sort of deal, but realized that the robots were actually sentient to a point, refused to kill them
Figured out a way to recode them (actually broke its link from “father”)
On his first try, was captured by a group, but before they were able to kill him he injected the code into one of the bots. The bot’s link broke, and saved uncle
