I’m incredibly curious about the impact of JC’s original dad because KR is such a pivotal character in the story, so I wonder if his original dad was pivotal at one point. One could assume not since they focus primarily on terminating either John or Sarah, but the question looms.

So who was the man that fathered JC in the original timeline before it got completely jacked up? Did he have any sort of presence or influence on JC’s life which led to JC becoming so “feared” by the machines? Is there a timeline where he fights for JC the way Sarah does? Or even alongside them?
