Looking for Dean/Cas recs

I started watching Agents of SHIELD live with a friend I work with when it premiered, and even though we both think it's fairly awful, we've continued watching it to mock it. I got him hooked on Supernatural as well because it comes on right afterward. In between our conversations about how bad AOS is, I found out that he's a fanboy (I mean, I knew he was an Avengers fanboy, but I found out he knows about fic and used to read a lot of it in SG1 and SGA). I ended up sending him a few recs for SPN fic and now he's hooked on Dean/Cas. I've already recced him everything I have bookmarked, but I haven't actively been reading SPN in a couple years. Anybody have any recent recs for Dean/Cas fic, or know of good rec lists I could pass along?
