If you watched Arrow's Suicide Squad episode two weeks ago, you may have noticed the brief, very silly, silhouetted cameo of a familiar-seeming character in pigtails.

Thanks to actor Michael Rowe, who plays Deadshot on the show, fans can now know what Harley Quinn, as portrayed by actress Cassidy Alexa, looked like out in the light. That's right, folks, they put her in the makeup and everything. Check out Rowe's Instagram snap after the jump.

Does this mean ol' Harl will be popping up in future episodes? Probably not, according to executive producer Marc Guggenheim. In an interview with Collider, he said:

I want to manage expectations with respect to Harley Quinn. She was always intended to be an Easter egg. I don’t want people to go in with incorrect expectations and walk away from Episode 16 disappointed. But there is an element to the Easter egg that was not spoiled by the promo, that I think people will find a lot of fun.

That element almost certainly had to be that Harley's voice was supplied by actress Tara Strong, who portrayed the character in Batman: Arkham City. (Voice actress Arleen Sorkin famously brought the character to life in her first appearances on Batman: The Animated Series.)
