At an unknown period in time, this man consented to possession by the angel Ishim. Ishim used this man as his vessel during his dealings with Lily Sunder and the murder of her angel husband Akobel and her daughter May in 1901.
Over a hundred years later, in 2017, Ishim still possessed this same vessel with Mirabel possessing the same vessel from 1901 as well. Castiel, who had been with them in 1901, had switched from a female vessel to a male vessel and expressed surprise that his two fellow angels still had the same vessels. Later, Castiel kills Ishim and thus his vessel with an angel blade to save Lily Sunder's life.
