The final season of Supernatural shows Chuck/God to be the big-bad. Chuck entered the scene as an awkward writer,  first presumed to be a prophet. His favorite topic was the Sam and Dean storyline. Chuck was their ally and friend, literally writing himself into the story. Later, he's revealed to be God, and he supports Sam and Dean. His obsession with Sam and Dean is so deep that he has created several drafts/worlds of their story, wanting their story to end in a classic biblical sibling-tragedy.

During all this time, Castiel is with Sam and Dean. One would think that he would be closer to Chuck/God since he's an angel, but their relationship remains one of confusion and mystery.

Why Does Castiel Not Realize That Chuck Is God?

At one point, Castiel has a crisis of faith. He has been an angel that obeys orders, but he begins to doubt where those orders are coming from. He decides to seek out God/Chuck, borrowing Dean's necklace that's supposed to act as a compass to God.

When Chuck enters the narrative, Castiel sees Chuck as a prophet, but he acknowledges that it's weird since Chuck's name wasn't written. Matter-of-fact, all of the angels see Chuck as a normal prophet. One would think with their father so close, the angels (including Castiel) would have realized that Chuck was God all along.

Why Does Castiel Still Have Powers?

At one point, Chuck/God takes away the extra powers (i.e. strength) that he gifted Dean and Sam. This renders Dean and Sam pretty vulnerable, realizing that they had taken their abilities for granted. Sam even attempts to take a pan out of the oven with his bare hands, not realizing that he needs an oven mitt. Dean gets cavities. It takes a special gift from the Goddess Fortuna to get some of their old mojo back.

Meanwhile, Castiel doesn't need to broker such a deal. His powers, including his healing powers, are still intact. Was this an oversight or does Chuck/God not have as much power over Castiel as he does over the Winchesters?

 Why Was Chuck/God Not Upset When Castiel Tried to Be God?

After Castiel's disillusionment and disappointment about his father, he decides to become God. This launches the time when Castiel, extremely self-righteous and untethered, becomes the big-bad. He kills innocents and lets out the Leviathans. Chuck/God has shown himself to be petty--obsessed with authorship, his power, and his stories. He's worried about Jack being a power that he can't control.

Yet, he doesn't get jealous or upset when Castiel claims his name? This seems unusual, considering what fans know about Chuck/God these past couple seasons.

Why Is Castiel's Story of Little Importance to Chuck/God?

Chuck/God is obsessed with Sam and Dean. It could be because they represent the classic biblical sibling story, or it could be that it is because they have constantly challenged the narratives that they were given. No matter how you look at it, this is one obsessed author.

Yet, there is little intrigue about Castiel's story and evolution. Castiel has also escaped the narrative that was meant for him. He's questioned and doubted. He had a romantic partner in a demon (for a time). His angel status was taken away, and then he got it back. Still, Chuck/God doesn't focus on Castiel. That may be a problem in the long-term because it does seem that Castiel has something up his sleeve, another potential way to end Chuck/God without having to sacrifice Jack.

Does Castiel Still Consider Chuck/God His Dad?

In earlier seasons, Castiel felt a deep desire to find his father. Dean could sympathize since he also had grown up with a somewhat absent father. For Castiel, it almost seems that he feels he will be able to make sense of his own purpose and existence if he finds God.

However, when Chuck is revealed to be God, it doesn't seem to matter to Castiel that much. After all this hunting and feeling disappointed, did Castiel decide that Chuck/God wasn't his father? Then does he no longer consider Chuck/God--dad?

Why Is There No Connection/Affection Between The Two?

Even Lucifer feels something for Chuck/God. He feels both anger and insecurity, which he masks in humor. In a more human moment, Lucifer admits to Sister Jo that he wants to be a better father than Chuck/God was to him. Lucifer wants his father's love and pride, but he feels rejected. Castiel seems to want none of that acceptance. Chuck/God's opinion of him doesn't seem to matter.

It will neither break or make him. The two are distant. For family, this seems strange. Castiel and Chuck/God might as well be strangers.

Is Chuck/God Building Castiel's Narrative, Too?

In some ways, it seems that Chuck/God had been building part of Castiel's narrative. After all, Castiel was a soldier of God. Also, it was he who was tasked to bring Dean out of hell. This suggests that Chuck/God wanted to have Castiel in the lives of the Winchesters.

However, since then, Castiel seems to have created his own narrative with the help of Jack. He was in the Big Empty and woke up, all because of Jack's power. He was made into an angel again, but he still retained his human feelings. Chuck/God's role in Castiel's narrative is unclear. Whereas Chuck/God was obsessed with Lucifer and Michael (making multiple versions) and Sam and Dean, Castiel is the side character with a larger narrative arc that he was first given.

Are There Multiple Castiels?

While there are many versions of Sam and Dean as well as Lucifer and Michael, there seem to be very few versions of Castiel. It's even suggested that there are more versions of Mary and Bobby. Did God/Chuck go through as many drafts with Castiel, perhaps ones that viewers haven't seen?

Does Chuck/God see Castiel as an important character or just merely a plot device to keep the brothers together? Once again, his authorship in Castiel's story is unclear.

Why Are They In So Few Scenes Together?

These two are rarely together in scenes. In fact, they are only together when they are with other people, namely Sam and Dean. It's hard to understand their relationship when fans can't see them together. This makes the two not seem close at all. They aren't really important to each other.

Is this an example of Chuck/God dismissing Castiel? Or is this an example of Castiel moving on with his story and reinventing himself as a member of the Winchester family, rather than the heavenly family?

Why Is Castiel Not Upset About His Father's Impending Death?

In Season 15, Sam and Dean are trying to figure out how to kill Chuck/God. On top of that, Jack is brought back to life for the same purpose: Kill Chuck/God. Castiel seems to have no hesitation about the need to kill his father. In fact, he seems to have no regret or sad emotions about it.

All said, Chuck/God is his father--someone he once tried so hard to find. Are viewers to believe that he doesn't have any mixed feelings about Chuck/God's upcoming death?
