If you continue reading the thread, you can see I already explained I hadn’t read the story completely, as I was watching the Space Shuttle Liftoff Prep. BTW, it was postponed for 24 hours.
Another poster explained that the story went on to say that Pops might have gotten some prostitute knocked up, then had his daughter adopt the baby.
Which, IMHO, is much more far-fetched than believing the incest storyline.
At any rate, it was my fault for not having read the complete story.
