It was a race for the ages between two iconic TV cars, but the Mystery Machine didn't even let Dean rev the Impala's engine.“A Night of Fright is No Delight”The episode was an actual Scooby-Doo, Where Are You! Episode from the show's first season in 1970. The mystery-solving, talking dog inherited a fortune from a mysterious Southern colonel whom he had previously saved from drowning. But to get the money, Scooby and the colonel's family members have to spend a night in his creepy old mansion.Castiel: “I’ve once led armies, and now I’m stuck with a Philistine and a talking dog.”Castiel shows up animated, too, and gets paired with Scooby and Shaggy as the groups search for clues on the scary (real) phantom that's haunting the mansion.Dean: “Scooby could die! And that’s not happening. Not on my watch. I’d take a bullet for that dog.”Sam, Dean and the Scooby gang realize that the phantom is real, and not just some "unscrupulous real-estate developer" in a mask. Unlike in the original Scooby-Doo show, Scoobynatural has animated death and dismemberment and Shaggy even breaks and arm, prompting the Scooby gang to have an existential crisis.The CW/Warner Bros. Entertainment Inc.“Together, we’re going to take down this phantom.”The iconic Scooby-Doo theme song plays while the two groups run around the mansion trying to escape the ghost. But in the end, Sam and Dean equip the Scooby gang with ghost-hunting essentials like salt, iron, weapons and holy water. Once they trap the spirit in a salt circle, it reveals itself to be a tormented young child who has been used by "The Bad Man" from the Pawn shop. He forces the spirit to torment property owners so they'll sell their buildings for a lower price.Velma: “I told you, you big lug, there’s no such thing as the supernatural.”To help keep the young boy spirit safe, Sam and Dean go back on their word and tell the Scooby gang they were wrong — ghosts aren't real. This line from Velma prompts a fourth wall-breaking side-eye from Castiel.Velma: “Those shoulders! Jenkies!”Before Sam, Dean and Castiel return to their three-dimensional forms, Velma — who's been crushing hard on Sam and his muscular shoulders the whole episode — kisses him.Misha Collins as Castiel, Jared Padalecki as Sam and Jensen Ackles as Dean (Dean Buscher/The CW)“Is that an ascot?”Dean dons a new fashion accessory to complement his flannel shirts, jeans and a leather jacket — a shiny red ascot.More TV: Weird, woeful 'Series of Unfortunate Events' is still unlike anything else on televisionInterview: Chrissy Metz talks 'This Is Us,' her painful Florida childhoodContact Chelsea Tatham at [email protected] Follow @chelseatatham.
