Episode 17 & 18

There's a Metallica song called The Memory Remains, and it's about a celebrity fading into obscurity, which drives her mad.

Here's an update on the Episode 18 summary:

SUPERNATURAL 12.18 “The Memory Remains”: Sam (Jared Padalecki) and Dean (Jensen Ackles) investigate a missing person’s case in a small town. The lead witness tells the Winchesters the attacker was a man with the head of a goat. Sam and Dean aren’t sure what to believe but when the witness goes missing they realize the town is hiding a dark secret. Phil Sgriccia directed the episode written by John Bring.

I'm not really sure what to say about this one. Head of a goat? I guess there are two ways it could go. The witness was wrong in what he or she said/saw, or the witness was right. If the witness was right, then some monsters that have the head of a goat:

Chimera (fire breathing monster with the body of a lion and head of a goat)
Then you have the goat man in Kentucky with something akin to Jersey devil or Big Foot sightings. https://www.youtube.com/watch?v=M5CRxqvyeHk

I guess Pan, fauns, and sytr were depicted as top half human and bottom half goat (or horse), but that doesn't really seem to fit. Lucifer could sometimes be depicted as part goat, but since we've seen Lucifer not as a goat, I'm thinking that's not it.

Of course it could also just be somebody wearing a mask, like in Plush last year.

Also, maybe you could make this one for spoilers for Episode 18? There is already a thread for 16 and 17, so doing one for 18 might drum up more eyes and comments?

And it'd keep people who don't want to see spoilers from seeing any, since there aren't any spoiler tabs. I know a thread title for future episodes is probably self-explanatory, but sometimes people click without thinking if it's not clearly marked as having spoilers.
