"You know, though, S13 Dean makes a lot more sense with this deleted scene intact..." What do you mean by that?
This is the post, here.
Okay, so obviously the removal of scenes means that generally speaking when they’re considered for meta purposes they’re outlying data. The fact is that scenes are removed for all sorts of reasons: they aren’t perfect, they can’t afford the special effects in the final budget, the dialogue contradicts something. Typically it’s time constraints that swing the axe, which is why those are often scenes that creep back into the DVD extras and such. Sometimes only a few lines are cut in a scene, but sometimes it’s a lot more. But it can’t be considered canon, just like the scene where Crowley and Cas bicker over Dean, including the ‘boyfriend’ word drop.
So while we can look at it, and judge intent, it is outside of canon. But seriously it gives SO MUCH that was missing to clear this and later episodes up. This scene, for example, lays down enough information to fill in a lot of the “well why didn’t Lucifer just fly right into the bedroom” things, etc. It’s informative, and it’s heartfelt, and it lends a lot of emotional weight.
For example, Mary is discovering that her sons will fight to save the world, no matter the odds. Sure, she’s been vaguely aware of that, but the Men of Letters poured propaganda into her head about her sons during her capture. So Dean says “We have to stop him” and Mary says “Can you do that?” and Sam says “We have to try.” That’s their role, their job, what they’re good at–taking plan A and doing their best, even though the world seems like it’s determined to end.
Mary is understanding, of course, because she knows what it means to go out and fight the bad guy because nobody else is going to do it, but they are finally not at odds in this situation, and she says the line that Dean has been thinking all this season, and what we presume he’s thinking when his mourning for Cas ends: “I only just got you back. I can’t lose you.”
Dean, understanding this, steps forward to reassure her. He says “You won’t.”
And then BLAM he loses Cas. He loses Mary. He loses everything. And more importantly for Mary, Dean fails her in that moment. He doesn’t deliver. She has to step forward and save her boys herself.
For Sam and for Dean, then, if you were to take Season 13 into context with this conversation in mind, you have Sam and Dean who failed. Sam and Dean who keep failing. Sam and Dean who still haven’t made good on their promise that Mary. Won’t. Lose. Them. Because she has. She’s lost them. They’ve lost her, sure, but this conversation makes the frustration less selfish and more about what Mary asked for, because Mary needs them, is trapped in the AU, they know she’s still alive (Dean is more aware), in grave peril from the angels, and that she, inevitably, thinks she lost them. With that in mind, no wonder it’s killing Dean, it’s how he’s felt his entire life about her.
There’s more to take from it, because I only just saw the video, and I think it would be more impactful on rewatch. But also sadly it’s still a deleted scene.
