The Flash hasn't even debuted on the CW, but details about the show are coming faster than it's titular speedster. Now Huffington Post reports the highly anticipated series will include a gay character.

Not only will Felicity Smoak (Emily Bett Rickards) of "Arrow" appear on the fourth episode of the first season of "The Flash," but the eighth episodes of both CW shows will make up a "mega-crossover event," in the words of executive producer Greg Berlanti.

Greg Berlanti and Andrew Kreisberg, the executive producers for both Flash and Arrow, also teased a "mega-crossover event" between the two superhero series. "We have the cameo crossover, the big crossover and then the epic crossover," Kreisberg said. Arrow regular Felicity Smoake (Andrew Kreisberg) will also be a major presence in Episode 4.

As for that gay character on Flash, who will debut in the first half of Season One, the creators are keeping details close to the vest. Berlanti already announced Patrick Sabongui will play David Singh, a supervisor at the Central City crime lab who is openly gay in the Flash comic, but this will be a separate character.

Wentworth Miller, who came out in January, has been cast as Captain Cold, but the sub-zero villain is staunchly hetero in the comics.

The most obvious choice would be Hartley Rathaway, a.k.a. the Pied Piper, a reformed villain who came out as gay in the comics some years back. And we've even got a brilliant casting choice: Out soccer star Robbie Rogers. He's already expressed an interest in acting,  he's got the physicality for fight scenes and he even looks like the Piper.

Plus, he's Greg Berlanti's boyfriend—which realistically can't hurt.

Flash debuts on the CW on October 7.  Arrow returns on October 8
