There’s a strong social aspect when it comes to hunting and while Cas is more than capable of taking down these monsters, it’s the social interactions in finding that info he’s still learning. And it certainly doesn’t help when he’s distracted and wracking his brain with how to save the boys and how he believes he’s the blame for everything that happened. Cas is not weak or stupid. This is just more evidence that Cas isn’t fine. Anyway, just my two cents. Feel free to ignore this rambling! 2/2
I have nothing to add, this is all I wanted to say.
