There’s been so many things said already about that scene, but I just can’t stress enough how important a cerain little detail was to me.
Let me try, anyway.
Heaven’s atomic clock-accurate timing, you know. There is this one line that points it out perfectly in case someone hadn’t noticed (although everything about the scene was so blatant that everyone and their grandma’s ugly dog could see it).
Dwight: Rod rides a stool here most days.
To gather everything we’ve got about this certain top priority assignment and its circumstances up, Dwight has already been acquainted with Rod for a long while now. In fact, Rod spends most of his time in this bar, and, considering that the owner of the place thought him to be important enough to introduce him to the lady, I believe we can take for a fact that the men think of each other as buddies already. You don’t spend load of your evenings sitting next to the bartender in an empty bar if you don’t like him. You don’t introduce a customer if it’s just a customer.
So, they already know each other and they had the time to become friends. They do have a bond of some sort. But apparently, whatever really runs the universe decides that it’s not enough.
Sounds like anyone we know?
But that’s one thing. There’s still something way more peculiar about this deal, lemme tell you. Considering the fact that Dwight and Rod had already spent a fair amount of time in each other’s company, I find it more than intriguing, that Heaven not only called this case a one of higher import (really, in times of thick political games, not long after a system-wrenching authoritarian’s massacre, in the general atmosphere of complete chaos) - it has been ordered to suddenly make these two already acquainted men fall in love, and it was scheduled to happen in an exact place, in a very precise moment.
Because, if the time and location weren’t all that relevant:
Aim but not shoot. Why? Because of the timing. Because of The Rules. And what are The Rules? Well, this and the previous episodes make it clear to both Dean and Cas. They give out the answers for their own two questions, respectively.
Castiel: …offspring of an angel and a human?I thought that wasn’t allowed.
Metatron: It’s not.
So, apparently, Castiel not only had been giving thought to the subject already, but he also thought it relevant enough to ask the “better informed” Angel about it. The way he asked it, though, kind of seemed as if he tried to find a loophole in the law. In fact, he did try to justify the Nephilim’s existence, by proxy at least partially justifying the whole relationship that had brought that women to life.
Metatron outright states that there is no possible way to excuse an Angel and a Human becoming this close on this level. It’s not his whim, it’s in The Rules, the one made The Force That Says The Final Amen Or The Final No To Things (which, for short, we’re gonna call Carver, since starting from season 8 - he’s God and The Rules).
But it’s not the final word of an answer to Cas’s question, not yet.
Having established that a Man and an Angel cannot lie down with each other, in the next episode the only possible loophole is given:
Castiel stops being an an Angel. He becomes Human.
But before that happens, he is vaguely reminded somewhere along the way that a Man loving intimately another Man is not only not wrong, but it is necessary and blessed.
That part was not meant for Cas, not really. That was the answer for Dean’s ultimate question:
Susan: …you just look the type. So, a king-size bed?
Sam: What? No, no, no. We’re just brothers.
Susan: Oh, I’m so sorry.
And in theory, that could be it. The mistake is fixed. Sam drops it, Susan drops, both content to have everything explained, but
Dean: What did you mean that we looked the type?
But the poor lad doesn’t get the answer, because, no one except for him is interested in the subject anymore. They’ve got everything clear. Dean doesn’t, so he goes on with the issue, even though he and Sam are obviously in the middle of discussing the case:
Dean: Of course, the most troubling question is, Why do these people assume we’re gay?
And this is somehow not even a little troubling for Sam, he doesn’t even put himself into the explanation, he addresses Dean’s issue alone:
Sam: You are kind of butch. Probably think you’re overcompensating.
And, my, he really, really was.
Dean’s million dollar question: Can you love a man and still be a man?
Because John had taught him that a man has to be a macho, a ladies-man, a tough, rough ideal for manly. And it didn’t really go well with what Dean really was. Of course, as time passed Dean learned to be more and more comfortable with himself, but that small John-made wound in his head still ached, especially with Cas around. So Dean kept using it as an excuse for trying to remain as emotionally uninvested as he wanted to be.
And once more, it was a matter of timing. It was obligatory for Dean to get hit with that Final Answer right in the face in that exact moment because a second ago, Dean was preparing himself to let go of Cas for the Angel’s sake. And if I had spare money I would bet that Dean would internally excuse himself with “it wouldn’t work because we’re both dudes, so” as well. E.T. could refer not only to Cas being another species, but also that the fact they were both the same gender, is somehow making the case different, unnatural, impossible.
But the Force said, in the last possible moment, before you justify your quitting with your bullshit, let me explain you a thing.
And Lo, it spoke yes, Dean, you so fucking can be the dudest dude to ever dude and still like dudes. Just look at those dudes. How manly and cool they are. One of them is you in twenty years if you don’t quit the burgers. Oh, and by the way, God says hi.
And it was also vital that at that moment Cas was there, because Dean had the chance to look back at Cas, notice the similiarites and also the fact that Cas seemed totally okay with that sight.
In fact, Cas most likely already knew. He could tell the lady was the Cupid, so he knew what was about to happen from the begining. On a side note, it makes me wonder what Cas could make of Dean’s “five minutes of every porn I’ve seen” comment in this context. Perhaps Castiel does not even try to get a correcting statement from Dean because he already knows in which ways his Righteous Man swings.
But to get back to the point. Dean, right before getting separated with Cas once more, learns that it’s fine. He can take the no homo argument off his list. But the other one is still a valid point: he’s an Angel and he keeps flying away.
But before the clock strikes midnight, The Power Says to Dean: but now he’s not.Go find him, go get him.
In other words, the bar scene and Heaven’s/Fate’s/Carver’s precise involvement was foreshadowing, but also winning over Metatron’s “find a wife, make babies”.
Metatron can say shit, he’s nothing but an usurper after all. It was the highest power that flat out told Dean to find the husband, make a family.
