I am looking for two stories right now.

The first one was long- at least 30 parts, and not finished when I lost track of it. I believe it was set during season five- after 5.10, I believe. Dean is hurt- brain in a blender hurt- and Castiel realizes he can fix it if Sam drinks angel blood. It develops into a threesome fic, and Anna eventually showed up. I think the team eventually started looking for help from other gods. Any help?

The second one- honestly, all I remember is that Sam and Dean are on trial, and the prosecutor asked a kid witness if Dean shared anything "secret" with the kid. The kid says yes, and then answers that the secret was "ZEPPELIN RULES!" (or rocks, can't remember which).

Hope you all can help!
