Yesterday’s Supernatural panel at the San Diego Comic Con had an exciting piece of news for fans of the long-running WB/CW series. A spin-off series is currently in development at The CW.

The current plan is to introduce a new character who would serve as an anchor for this new series in or around episode 20 of Supernatural’s current season. That episode would effectively be a backdoor pilot to this spin-off.
