Supernatural Cast: Where Are They Now?

Alexander Calvert was introduced in the Season 12 finale as Lucifer's Nephilim - that is half angel, half human - son, Jack. From here he would become a major character of the last few seasons of the show.

Before Supernatural, Alexander had a few recurring roles on other series. He portrayed Hunter Gibbs on The Returned alongside his character's daddy from Supernatural, Lucifer actor Mark Pellegrino. He also portrayed Lonnie Machin, aka the villain Anarky, in Arrow up until his character's demise in season 5

Calvert originally got his start in the TV reboot of the Stephen King thriller, Dead Zone, playing the 12-year-old version of Sean Patrick Flannery's Greg Stillson. Calvert has most recently been announced to play Thomas the Cat King in an upcoming series, Dead Boy Detectives alongside fellow Supernatural alum, Ruth Connell.

Dead Boy Detectives looks to be a spin-off of Doom Patrol and Calvert's character appears likely to be based off the Batman villain-turned-hero Thomas "Catman" Blake. He may also be combined with Karl "Cat King" Kyle, Catwoman's brother who appeared in a single comic back in 1952. Though at this stage very little about the series is confirmed.
