Also, because this is a SPN blog, I'll 1) note that this must be what it felt like to be translating the stupid tablets--long periods of absolutely incomprehension punctuated by sudden clarities.
Also, the Trans suffered (and continue to suffer) the worst out of every character in SPN, including Sam and Dean, and you can't change my mind. They worked Kevin nearly to death after abandoning him for a year, avoided all non-essential contact with him, refused to offer him safe harbor in a secure location (i.e. the bunker) even after he expressed his need/fear, and then got him actually killed. And they left Linda to be imprisoned/tortured by Crowley purely because they just assumed she was dead and could not be bothered to confirm until Kevin insisted, literally from beyond the Veil. The lives the Trans lived correspond directly to the ways Sam and Dean are deeply inadequate to the tasks laid before them.
LET ME BE CLEAR HERE, I don't think anyone should--or can--be adequate to the tasks laid before Sam and Dean. The whole point is that it's just not possible. I also think it's totally understandable that all this would play out in the way that it did, and that Sam and Dean would make the choices they did, consciously or unconsciously. I don't think it could happen differently, or that it should have. I doubt I'd want it to, frankly. I just think it's important to acknowledge that Sam and Dean have really fucked some shit up, in ways that do not begin to approach "but it was for the grater good" or "but it balances out." The moments where they are truly awful human beings are as profoundly important to how I feel about Sam and Dean as their capacity for warmth, hope, and selflessness. <333333
