Yeah, Wikipedia's about as far as I know, though from the promo clips I assume Cas is injured somehow. They do love to have him spitting blood, don't they? I assume it's the mouth factor. And dear lord, this is like the episode with a thousand faces. According to Wikipedia, it's "The Song Remains the Same", and according to YouTube, it's "Back to the Future II". Keep it straight, people!

...How does the public even get episode names, anyways?

An aesc femslash fic? I am... very surprised I had not seen that before. I thought I'd pretty much exhausted her material, to be honest. Just goes to show. As for the fic itself: oh, how I wish it were longer! I like the little snippet of their life she shows, and I love the person Claire's grown up to become, and damn it, I want more.
