Adam/Samandriel
From Super-wiki
Adam/Samandiriel slash fanworks pairs the characters Adam Milligan and Samandiriel in a romantic or sexual relationship. The common name for this ship is Adamandiriel.
This pairing has only a small following, not surprising considering the two characters have never made contact in the show, let alone ever be in the same episode together. Many Adamandiriel stories center on Samandiriel rescuing Adam from Lucifer's Cage, much like when Castiel raised Dean Winchester from perdition. This pairing first arose after Samandiriel's first appearance in 8.02.
