McKinney will appear in Episode 12 as Henry, the paternal grandfather of the Winchester brothers. Much like Season 4’s “In the Beginning,” which introduced the maternal side of the fam, the installment deals with time travel. But rather than visiting the past, Sam and Dean will encounter Henry in the present.

John Winchester’s pop will provide “some insight into the life and the legacy of [his family], which is something that we as characters never really knew,” star Jensen Ackles tells HuffPost TV.

McKinney — who played Julie’s TA/love interest on FNL — has also appeared on Grey’s Anatomy and ER.
