Also, the Big Twist is pretty worthless unless you've never heard a story about cryogenic freezing. We don't know how much time elapsed between the bomb and Kellogg, or Kellogg and our escape. The Sole Survivor keeps thinking the second time skip is no time at all, despite being told right from the start that the total of the two time skips is "a bit over 210 years," according to Codsworth, one of the few NPCs who could reliably tell you. My first question after that was, "okay, so then how far back was the shooting, since the two add up to 210 years?" It's not reasonable at all to assume either time skip is short or long.
