I think that Shaggy and Googie should be friendly exes, like he shows up with the gang to hang out and they tell the How Shaggy Beat Dracula In A Drag Race story for the umpteenth time. Better friends than they were in a relationship.
Daphne and Velma could use another girl friend! Fred gets someone to infodump about traps to! Scooby gets someone who doesn't mind if he's dog or human, he's getting snacks! Shaggy gets another friend! She's the token human friend that shows up occasionally to me, the one person who knows WHAT the Scooby Gang are and doesn't care!
At least that's. Who she is. To me
googie's awesomeeee she should absolutely be the human friend
