I get the idea that after all the fighting these two have done, all the huge battles they've waged against the worst of the worst, that going out with something mundane would be seen as something poetic, but in that case, I would have rather they picked cancer, or even COVID-19. Not some rando vampire in a rando barn and a rusty old nail in the middle of nowhere, a few days after they took down GOD and replaced him with their own kid.
That all just made no sense to me. I think we all kind of accepted Dean to fall in battle, but like that? And then to TELL us about all the people in Heaven
