Crazy as it is to think of Arrow In Space, the emerald archer’s DC crossovers are no weirder than Supernatural hanging out with Scooby-Doo.
In the meantime, Supernatural Season 13 is gearing up for another spinoff, while both Arrow and Supernatural will reveal more at Comic-Con 2017.
It’s no stranger than any prior Supernatural concept episodes, which apart from Scooby-Doo have included musicals, meeting the real Jensen Ackles and Jared Padalecki, and Japanese game-shows.
Padalecki: Stephen’s a big guy … but I think he’d want some apple-boxes and stuff to stand on, so it might never happen.
