Forum:Dad Egbert is Problem Sleuth

I just came up with the weirdest theory ever. Dad is PS. Here are the reasons.

AD's, PS's AND PI'S Hats
Most likely you have noticed that there are hats identical to AD's and PI's in Dad's study. In my theory, the reason is that Spades Slick killed AD and PI. PS survived and changed his appearance and stopped being a problem sleuth to look like a normal person.

Dad's study is his study to John; the actual study is found in a secret passage trough the chimney. It's PS's study. Also, Jane likes detectives because of Dad. The hammer is also explained by this, with the PS videogame and other PS references in Homestuck.
