GUYS I THINK I HAVE AN IDEA ABOUT DECEIT'S NAME
Okay so I was watching embarrassing phases again and and at 16:35 patton says
"Uh, Logan! Did Derekson have anything to say about this?
And logan goes,
"You mean Erickson?" (Kinda offended but that's beside the point)
THEN Patton goes-
"Oh! Thats right! The only sons i can keep straight are my own" (and then he looks around as if he made a dad joke.)
I think Deceit's name is Derek.
Think about it. Patton refers to nearly everyone as his son. No one else picked up on it because they didn't know Deceit's name.
Patton would probably know about Deciet's name because lets face it, Patton would have a tea party & in-depth conversation about feelings with anyone.
I'm probs just rambling bit there has been foreshadowing like this before. Like in Why Do We Get Out of Bed in the Morning, the final idea for the game to play with Thomas's friends was with puppets. (The next episode was about puppets)
And if we go with the clues from the end card, Deceit took the Scooby doo tag from virgil's room.
(the initials on the Scooby doo tag are SD)
