Hey guys!

I'm looking for the angstiest, saddest, most heartcrushing deathfics you have, where Castiel is the one who dies. Because I'm a masochist.

I'd prefer if it was ~somewhat permanent, ie. not S09E03, and no Wincest unless it's Wincestiel please. AUs are great (though not Twist & Shout, I know of that one already :') ). Bonus for fic with the other angels making appearances too.

Thank you so much in advance!
