The CW's The Flash includes two gay characters and out actor Victor Garber.

Garber (Alias, Argo), who quietly came out gay last year by saying he was never in, will play Dr. Martin Stein, one half of the Firestorm entity from the DC Comics universe. Dr. Stein is a nuclear physicist devoted to his work in transmutation.

The CW's spin-off of Arrow premiered last week with Grant Gustin (Glee) playing Barry Allen, an awkward forensic crime scene assistant who gains super-human speed after being struck by lighting to become The Flash.

According to TVLine, the show includes two gay characters: villain The Pied Piper and Crime Lab Director David Singh.

Singh is played by Patrick Sabongui (The Cabin in the Woods, Godzilla), while The Pied Piper is played by Andy Mientus (Smash).

Mientus, 27, is openly gay and recently announced his engagement to his long-term boyfriend, Michael Arden, 31, who co-stars on the FX sitcom Anger Management.

Dr. Stein and The Pied Piper make their debut later in the season.
