Andrew Dabb referred to “his character,” which gives the impression that Jeffrey Dean Morgan will reprise the role that has made him a legend among Supernatural fans.
For a character who only contributed to 12 episodes of the series (only lending his voice in two of those) his legacy has continued to impact the Winchester boys and how they operate at saving people and hunting things.
Supernatural fans can undoubtedly enjoy speculating about who else might be back.
Interestingly, Dabb also teased “other surprise guest stars.”
