The new Supernatural spin-off will bare a lot of similarities to its parent series, but one thing that will be definitely missing is everybody's favorite angel. While Sam Jared Padalecki) and Dean Winchester (Jensen Ackles) will appear in the upcoming pilot (episode 20) and may make guest appearances on Tribes, Castiel (Misha Collins) will not.

"Yes there has [been discussion of that] and no, that wont be happening," Collins told TV Fanatic in regards to a potential Tribes appearance. "I think it's designed to be very standalone so they're not going to be bringing a lot of characters in. The characters that are introduced in the episode will be the spinoff series characters but they're not going to be carrying characters that have had long arcs on Supernatural over into the new show."
