The real reason Cas didn’t get that vampire
At first I was like WTF when Cas couldn’t kill a simple vampire. I mean, come on, this guy is a badass with eons of experience killing demons, he won the war against an archangel, Molotoved the devil, and has a ton of super powers.
Then I remembered… this was him last time Dean was missing:
And it makes a lot more sense. Cas didn’t fail on a hunt because he couldn’t find a vampire. I think he was too depressed and distracted by Dean being missing to hunt. Sure, he tried a bit, but I’m betting 90% of that hunt was him checking his phone, downing coffee and moping, listing for any hint of a prayer, and sitting in the car playing sad songs on repeat. Poor boy’s so smitten, he couldn’t even concentrate long enough to find a single blood sucker.
Yeah, and back then he was slowly dying from his grace burning out too, but it was depression helping him along there. Just like it’s been ptsd and depression since early s11 too…lying in bed, watching bad tv, too messed up to even leave the bunker to help Dean on a hunt…
But he didn’t have anything to fall back on here. He didn’t even have Sam, and the one time he’d contacted Mary when Sam and Dean first disappeared, she blamed him for not keeping them safe. (I mean she was scared and hurt and had felt left out that they didn’t call her for backup, but still… that hurt to hear from her).
So yeah. Basically I agree.
Not only is Cas depressed and adrift without Dean (or even Sam, really), he doesn’t even have enough human coping skills to recognize the fact that he’s depressed. He’s so much more at the mercy of his own feelings than a human would be, because they’re so alien to him, as well.
(yes, I know, he’s been human before, but he wasn’t supposed to feel this with his own grace back now, you know)
