I wonder if Cas was excited, walking into that room. He’d spent weeks on his own, months really, trauma after trauma layering on top of him, weighing him down. He was gravely injured, and he went to the one place he knew he would be safe; he went home. I wonder if when he got up that morning, feeling less like he was spilling out from a hole in his side, he lay back with a rare sense of contentment, because he was safe, because he was with his family. He knew it couldn’t last, but at least in that moment everything was okay, because he could see Dean again, could feel the glow of happiness he always feels around him. And when he got up to join his family, his heart was pounding because even when it all goes to shit, everything is better when he can be with Dean. I wonder if he was excited, happy, contented, for the first time in a while, to be able to see the love of his life.
And oh how quickly that happiness crumbled.
