#thats until one day BOOM KIDS STORM INTO HIS BACKYARD SCREAMING AND RUNNING AROUND CHASING BUGS AND HE WAS LIKE "GET OUTTA HERE YEW BRATS!'

One question, in his AU did William have some kind of trauma as a child or something like that in his past?

In the Springdad AU, William had a troubled childhood and when he grew up, became very cold and distant. He moved to a place where he could be left alone, in an attempt to find peace.
