Adam/Samandriel
From Super-wiki
Adam/Samandriel 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 at the moment, considering the two characters have never made contact in the show, let alone ever be in the same episode together. Many Adamandiriel fanfictions center on Samandiriel rescuing Adam from the cage, much like when Castiel raised Dean Winchester from perdition. This pairing first arose sometime after Samandriel's first appearance in 8.02.
