Author: @ayyysexual (cynder713 on AO3)
Pairing: Pre-Dean Winchester/Castiel
Summary: Cas, determined to prove that he can take the lead on a hunt, brings a case to the boys. It’s a siren, of course it’s a siren, and despite Dean’s protests they take it, with Cas offering to play the bait.
Notes: Thanks to Ayyysexual for the writing the awesome story and glad I was able to provide the artwork for it. :) It was a pleasure to do so.
