YMMV / Teenage Mutant Ninja Turtles 2003 S 3 E 12 The Lesson

• Captain Obvious Reveal: The boy the Turtles trained in the flashback being Casey wasn't hard to figure out. He had the same hair color, wore the same colors, and had the same Brooklyn accent. Him being referred to as "Arnold" wasn't much of a misdirection since his Given Name Reveal has already occurred in H.A.T.E.. That said, the show did try to cover this by updating Kid Casey's initial design from season 1◊ to a slightly different look◊.
