The SPN pentagram is a really pretty design, and I bet it goes well with the ouroboros. And hooray for multiple meanings~ I love it when things have personal symbolism on multiple levels.

I'm kinda the same re: spoilers and meh, but the potential of more Gabriel is almost tempting enough. ^.^ I'll have to wait a bit and see what they decide to do with him.

I think my main SPN ship is Gabriel/anybody who makes him happy. XD I like Cas and Dean, and Bobby and Crowley, and I know what you mean about Lucifer/Sam! It sneaks up on you. And I like Balthazar, but that may be due to Sebastian being hilarious.

Good luck on it!!
