The CW has passed on the "Supernatural" spinoff

[Phillyrider807]

Jo/Ellen, Meg and Henrickson was never gonna have a spinoff as the show wasn't big enough to grant a spinoff when those characters were on air.

Crowley and Charlie are easily the 2 best characters to base a spinoff around at this point. Even though i think Crowley is gonna die on Tues.

Crowley has no shot for the same reason that CW would never have done a Bobby/Rufus spinoff...Mark Shepherd does not fit the look of the star of a CW show. He's too old, too short, not buff and his hair is thinning.
Jo and Ellen lasted long enough to be given a spin-off since they didn't kill them until season 5 which was the height of the show's creative peak.

Jo/Ellen came back after 2 seasons to die in the mid season finale. Ash was already dead and the roadhouse was already destroyed by that time. They had no chance!! (Yea Ellen came back in season 6 and Jo came back in season 7... But they were dream and spirit versions)

And yea i agree about the reasoning u listed. Which is why i still think Charlie is the best contender for a spinoff. The supernatural fanbase LOVES Charlie.
