Supergirl Episode 7 “Human For A Day” Description & First Pics – With A Constantine Guest!

A beloved cast member from Constantine appears as another DC character — Jemm, Son of Saturn — in the December 7 episode of Supergirl!

Charles Halford, who played Chas in the short-lived NBC series and sadly didn’t get to come back when John Constantine returned on Arrow, plays the role of the alien character. Jemm is very cool… one could say he’s even truly outrageous! (Wait, that was Jem with one “M.” Our bad.)

Here’s how CBS describes the episode:

Kara and her friends must rely on their inner strength and courage when an earthquake strikes National City. Also, Alex’s mistrust of Hank reaches a breaking point when the earthquake traps them in the DEO with Jemm (Charles Halford), a powerful alien escapee, on SUPERGIRL, Monday, Dec. 7 (8:00-9:00 PM, ET/PT) on the CBS Television Network.

Guest stars in the episode, which is called “Human For A Day,” include Laura Benanti (Alura/Astra), Peter Facinelli (Maxwell Lord), Luke Macfarlane (Agent Donovan), Ashton Bingham (Senior Tech), David Lim (Agent Tsung), Ayo Sorrells (Agent Reynolds), Stephanie Arcila (Woman), Zhuair Haddad (Store Owner), Casey Strand (Reporter), and Bryan Lugo (Looter).

“Human For A Day” was written by Yahlin Chang and Ted Sullivan and is directed by Larry Teng.
