Headscratchers / Velma Meets the Original Velma

• One of the Velmas shown when Scooby mentions having tried "again, and again" at recreating the Gang only for Velma to remember is Scooby-Doo! Mystery Incorporated. That iteration of the series however gave an In-Universe explanation for Scooby's ability to talk, namely that he was the descendant of an animal that had been possessed by a member of an alien race known as the Anunnaki, meaning Velma shouldn't have had anything to trigger her memory in that iteration.
  • What the Velmas were actually remembering was not Scooby's ability to talk, but the existence of the other worlds and the different appearances and dead bodies of rest of the gang. In the current timeline, Scooby didn't even say anything before this Velma noticed that something was... wrong about him.
• Why aren't Scooby-Doo and Guess Who? or SCOOB! a part of the reboots?
  • They ostensibly are, we just don't get to see them; also the live action films (Which may be two different continuities), The 13 Ghostsof Scooby Doo and Shaggy & Scooby-Doo Get A Clue!
