Chuck as a writer, his 'favorite show'
Couple of thoughts, really. I'm not sure how other writers go about it, but when I plot out a story about original characters, usually I will have an idea about a specific plot point or story, then figure out my main character(s), and from there start building their back story, creating other characters that are needed to help tell the story, ect... the secondary characters and all the background stuff are created specifically for those main characters. So did Chuck create Castiel millenia ago, intentionally with his crack in his chassis, specifically for Dean? We know that John and Mary getting together was planned so that Sam and Dean could be born, and Cain said their lineage goes all the way back to Eden, so it could be assumed that Chuck was planning his 'favorite show' from way back then. So it doesn't seem outside the realm of possibility to me that he created all of the people who have had the biggest impact on their lives, like Bobby, Charlie, Kevin, and so on, just for these two characters, which makes those people seem more important to the narrative. But it's kind of mindblowing to think that all those thousands of years before Dean was even born, Chuck knew he was going to need a special angel, one that was just a bit different, who would be willing to walk away from heaven and millennia of being a soldier and not thinking for himself, and multiple brainwashings to 'fix' him and still be able to keep going, so he created Cas for Dean. Kind of like how he created Eve in the bible for Adam.
Chuck is a douche, but I think that is kind of cool. To add to the coolness of it, he created Castiel for this purpose so well that it actually backfired on him. Cas was able to stand up to God Himself and exercise his own free will. Chuck tried to drive them apart and he almost did, but in the end, they all defied Chuck and stayed together.
BTW, I just realized how awesome it is that Naomi used the phrase "came off the line with a crack in your chassis" for Cass because if you were speaking literally, you would be talking about a car. It sets up a metaphor or a parallel between Cas and Baby, and I really like that considering how deeply Dean loves Baby and how important she is. And how she has been completely totalled more than once, besides the little imperfections like the legos in the vent, the army man, and even the squeaky door, she also probably has some cracks in her chassis as well. And Dean loves her so much that he rebuilt her when most people would have scrapped her, and he kept the imperfections, he loved her probably even more after he had to weld those cracks back together so that she probably looks like she has scars underneath.
Wow. Dean really is better than Chuck. By this point, he basically is Baby's creator the same way Chuck is the creator of everyone and everything else, but he never gave up on her or turned his back on her. He knew she wasn't perfect and he didn't care. He showed more care for a single inanimate object than Chuck has shown for all of his creations. And the episode 'Baby' kind of makes it seem like maybe she isn't completely inanimate, and somehow returns that love when she takes such a beating and struggles to start, but she does because he asks her to, and if she were sentient, she would have faith that no matter what he had to put her through, he was going to fix it and make it up to her.
So, that was rambling and weird, but I had too much coffee.
