For my friend Sheila who needed a pick-me-up yesterday. And a reminder about certain things. No real spoilers unless you don't know who Castiel is. And although Red didn't beta this, I want to thank her anyways because she puts up with me when I am being neurotic. Tee hee, I think my author's note is longer than the ramble! Enjoy!

The things he can't be

Castiel can be many things to Dean.

A friend.

A confidante.

A partner.

An angel.

But there is one thing he can never be.

His brother.

Sam.

Castiel can share many things with Dean.

A hunt.

A cause.

Pain.

But there is one thing he can never share.

Blood.

But Sam can share his...

With them both.
