The Flash Earth-Two Photos

The Flash First Look: Earth-Two's Killer Caitlin, Singing Joe, Gun-Wielding Iris

Forget the upcoming crossover between The Flash and Supergirl: It’s the CW series’ trip to Earth-Two in next Tuesday’s episode that may yield some singing.

In the following newly released photos, Broadway vet Jesse L. Martin appears to show off his impressive pipes as Joe West’s doppelganger.

Elsewhere, Caitlin and Ronnie wreck havoc as the villainous twosome Killer Frost and Deathstorm, while Iris is no damsel in distress in the face of danger. Plus: Someone who died on Arrow makes a surprise return!
