Which moment in the game stands out as dark and disturbing. Mine is Sunflower Summers. She was a hippy protestor and the military tricked her into meeting with them where they gunned her down.

There's no evidence she was gunned down. The Caves back then wouldn't have been reachable without a lot of twisting and turning underground. It's possible she tried to get away from the police, but considering she's by items, it's more likely she tried to make a safe place after the bombs dropped and died over time.
