Oh please, oh please, oh please.
You said "hopeful drabble", right? *whimpers* Please continue, have Sam help and find Gabriel.
Because it IS going to happen - RSJ tweeted about a week or so ago that he was in the writer's room at Supernatural headquarters and "Trickster?" was the only thing written on a board. ( instagram p/bE28qJS8PQ/)
Seriously, if it doesn't happen after this news I think I'm going to scream and cry and die a bit inside and then go protest with flaming pitch fork.

But you should definitely write a piece for how Gabriel comes back because it is greatly needed in this little universe you've created and I would love to see your take on it!

I'll help Sam! Anything to get you two back together! Excellent job, I really felt the emotion here.

Oh man, I wanted this to happen in cannon so bad! There has to be something in that library that could help him!

ooohhhmyygood. Cue crying meme.

I'm hoping about this as well. :)

I went "YAY!" when I saw this story was about the Men of Letters.
Then "SQUEE!" when I saw it was Sabriel.
Nice work!
