Chuck Hansen and Stacker Pentecost walking side-by-side in Pacific Rim look like someone granted a wish for Human!Impala and accidentally brought Castiel’s Lincoln Continental to life as well. Pimpmobile was only side-swiped by the spell, that’s why he’s already more green than gold, kind of the way that fake gold turns skin green, and no my reasoning doesn't really add up if you think about it, but are you going to argue with my flimsy oxidation headcanon when we could instead be considering the Dean/Cas implications of this?
Dean trying to be smooth to impress Baby, because Winchester Logic ignores that Baby knows everything about him already.
Dean asking what the hell’s wrong with that other car because it doesn't look right and it’s acting weird.
Sam telling Dean not to be rude to the Lincoln (+ the Lincoln later messing with Dean about why Sam told him to be nice. “Sam drove me.”)
Dean telling Cas “I’m just saying, your car looks like he could use a paint job.” The Lincoln himself asking if Dean wants to give him that paint job.
Cas casually saying that golds and greens are wonderfully linked, for example the way lakes of gold contribute to the green of Dean’s eyes.
Lincoln asking if he’s the same green-gold of Dean’s eyes; Baby saving Dean from more embarrassment by cutting in to tease the other car.
Dean getting frustrated at how much Cas continues to like the Lincoln, even when Human!Lincoln is super obnoxious.
Dean’s horror when he thinks Castiel’s car is going to corrupt Baby.
Sam asking Dean if he’s jealous that Baby is spending so much time with another car instead of with Dean.
Dean deflecting but eventually calling the age difference into question. “Come on, Sammy, Linc was born in 1978. He’s way too young for Baby.”
Sam pointing out that Dean has spent a great amount of time with an angel who has a few centuries on all of them; Sam also pointing out that Dean is closest in age to the Lincoln, so under his logic he should spend time with Human!Lincoln instead of anyone else...then Sam realizing mid-sentence that all of this age difference talk came about because Dean thinks the cars are more-than-friends. Sam’s just like WTF, Dean, are you reading a sexual relationship onto two cars?
Charlie and Cas and the cars all cosplaying while Dean and Sam argue about that.
“You think I woke up expecting to talk about Cas’ car and its sex drive? 'Cuz I could’ve done without knowing all this; trust me, that car wants to bang something. If you’d heard how he talked about you driving him--.” “Driving a car is not sexual, Dean. That’s like saying if we’re inside of a haunted house then we’re having sex with the house. I mean, I got turned into a car six years ago. You were inside me when we had to drive anywhere; there wasn’t anything sexual about that.” Meanwhile, Dean had interrupted Sam as soon as he said inside me, just “Why?! Why, would you word it like that?”
Sam telling Dean that he has the perfect excuse to go hit on the Impala, under the pretense of confirming his theory about the Lincoln.
Baby basically phone-sexing Dean in person by talking about how he wants Dean to have sex on top of him, the way he used to do on the hood and in the backseat, to see how it feels to have Dean-plus-one on top of him when he’s human.
Dean asking if Baby had a favorite Dean-hookup and Baby saying that he was partial to Anna, but only because she’d been the only angel so far and Baby has grown fond of angels.
