Castiel could be on a direct path to godhood ifSupernaturalseason 16 ever comes to pass. Portrayed by Misha Collins since season 4, Castiel did not receive an especially satisfying ending inSupernatural’s series finale- largely because Castiel was not actually inSupernatural’s season finale. The beige-clad angel sacrificed himself to save Dean Winchester, dramatically declared his love, then found himself taken away by the Empty. A single line inSupernatural’s finale confirms that Castiel ultimately survived, but the character himself remained frustratingly absent.
Fortunately for Castiel, a second chance is potentially on the horizon. The cancelation ofThe Winchestersleft aSupernatural-shaped hole in the universe, and Jensen Ackles and Jared Padalecki have both expressed interest in continuing the story of the Winchester brothers under the right circumstances. Given Castiel’s importance to the franchise and his less-than-ideal exit in season 15, Misha Collins would very likely be involved with anyfutureSupernaturalrevival, whatever form that takes. Should Castiel’s grand comeback become a reality, he should also prepare for a celestial promotion.

If It Happens, Supernatural Season 16 Would Need To Kill Off Jack
Jack Is Way Too Powerful To Stay Alive
Supernaturalended with the defeat of Chuck Shurley, more commonly known as God, and Jack Kline stepping up as a replacement. Jack qualified on the basis of being Lucifer’s son, but the changeover confirmed"God" is merely a title inSupernatural’s universe, and can be passed from one candidate to the next. As far as Sam and Dean Winchester are concerned, Jack’s ascension is the very definition of having friends in high places, and so it proved inThe Winchesterswhen God bent the universe’s rules to let Dean hop timelines and fight the Akrida.
ForSupernaturalseason 16 to have any kind of stakes, Jack would need to be killed off very quickly.

Upon receiving his divine power-up, Jack made a deliberate decision to let free will reign, avoiding the kind of interference his predecessor was so fond of. At the same time, Jack is never going to abandon his family, and the Winchesters - Dean especially - became surrogate father figures throughoutSupernatural’s later seasons.As long as Jack is God, therefore, Sam and Dean will always have the most powerful figure in existence on their team, and the Winchesters' universe will never come under any realistic cosmic threat.
10 Reasons Supernatural Season 16 Would Be A Bad Idea
Supernatural is one of the best shows to ever appear on The CW, but the show should not be revived with a season 16 for numerous reasons.
ForSupernaturalseason 16 to have any kind of stakes, Jack would need to be killed off very quickly. He is simply too powerful of an ally for Sam and Dean to have around, too convenient a plot device to remain on the board if the story has any hope of continuing.

Castiel Is The Only God Replacement That Makes Sense For Supernatural
Castiel’s Résumé Makes Him The Obvious Choice
IfSupernaturalseason 16 kills Jack, Castiel is the only character who makes sense as a replacement. Alongside the Winchesters, Castiel served as a third parent-like figure to Jack, andSupernatural’s series finale subtly hinted that the angel had become a special advisor or second-in-command to the new God. The moment in question came during Dean and Bobby’s reunion, with the latter revealing how Castiel personally helped Jack restore calm and order to Heaven. IfCastiel is effectively Jack’s right-hand-angel whenSupernaturalends, Misha Collins' character is naturally next in line to become God should Jack die.
AsSupernaturalprogressed and various Winchesterisms seeped into his angelic DNA, Cass learned to balance his sense of biblical responsibility with human empathy.

Being thrust into Heaven’s top job would give Castiel a fascinating arc in any futureSupernaturalrevival. Cass would have all the responsibilities of God, but wouldn’t necessarily get all of Jack’s awesome powers. Castiel was one of the various angels who helped oversee Heaven when God was missing inSupernatural’s earlier seasons, but between civil war and the Metatron incident, his efforts mostly failed.Taking over Heaven after Jack’s death would represent a shot at atonement for Castiel- one final chance to prove himself capable of leading.
Castiel has always been a character driven by duty to his kind, but asSupernaturalprogressed and various Winchesterisms seeped into his angelic DNA, Cass learned to balance his sense of biblical responsibility with human empathy. That emotional and moral growth makes Castiel symbolically perfect to become the new God ofSupernatural’s multiverse- a character who feels the weight of responsibility that comes from protecting all creation, but still understands the value of a single human life.

Supernaturalsettled the “Cass vs. Cas” spelling debate by showing the double-S spelling onscreen on several occasions.
Jack meets that criteria too, of course, but after audiences watched Castiel make those moral strides onscreen across an 11-year period, his elevation to godhood would arguably be more satisfying. At the very least, becoming God would be a better ending than Castiel received inSupernaturalseason 15.
How Castiel Becoming God Would Change His Relationship With Dean
Can God Be In Love?
Aside from potentially becoming God,Castiel’s other major storyline inSupernaturalseason 16 would, of course, be his relationship with Dean Winchester. Despite some ambiguity over the intention behind his words, Castiel appeared to declare his love for Dean before being taken by the Empty in season 15. Dean was left with no opportunity to respond, and the matter has never been mentioned since, not inSupernatural’s series finale, nor inThe Winchesters. If it happens, resolvingDean and Castiel’s love storywould be somewhere near the top ofSupernaturalseason 16’s to-do list.
If Supernatural Season 16 Doesn’t Fix This 13-Year Dean Injustice, There’s No Point Doing It
If Supernatural season 16 ever happens, this 13-year injustice must be addressed, otherwise there is little point in the show returning at all.
Castiel becoming God would have a huge bearing on any potential love story with Dean. On one hand,the angel may decide that running Heaven takes priority over personal desires, meaning any romantic designs for Dean must once again go unrealized. On the other hand, Dean being dead and Castiel becoming God means that - practically, at least - a “happily ever after” for the pair is plausible. He might face accusations of playing favorites, but God Castiel could, whenSupernaturalseason 16 ends, settle down with Dean in a nice Heavenly cottage to enjoy eternity together.
