The flashback conjured by Laurie is forcing you to be a jester about 400 pages later, where it appears you're ass deep in some convoluted backstory arc. What's going on here now?
This is back when Poffy was alive, but you don't remember doing this. Wait, now that you think about it, there was a weird arc when Poffy was alive but disappeared from the bunker for several months. You suspect what really happened was some future version of you time traveled back to that moment and recruited Poffy to go on a side quest. That would explain why Poffy was changed forever after he returned, seeming to be irrevocably traumatized. This dramatically affected your relationship thereafter, which then spiraled into the fateful Incident, which we don't talk about.
