'The Flash' Season 2 Spoilers: Escape from Earth-2 Featurette [VIDEO]

"The Flash" has been heating up television screens during their sophomore season, dominating the ratings of the 18 to 49 demographic since its first crossover episode with "Arrow" back in December 2014, Variety reports. The show saw a 1.6 rating/5 share in adults aged 18 to 49, amounting to four million viewers in total.

If this is any indication, a third season of "The Flash" is definitely a go. Fans are also gearing up for the highly anticipated crossover between "The Flash" and "Supergirl," which will find Barry Allen entering the world of National City come March. Meanwhile, The CW has released a featurette for the upcoming 14th episode of
"The Flash" titled "Escape from Earth-2."

"At the end of episode 13, Zoom has captured Barry. They (Earth-1 Cisco and Earth-2 Harry) don't know where Zoom's lair is," executive producer Aaron Helbing told Comic Book. "They don't know how to find him, so they turn to CSI, Earth-2 Barry Allen to lead the way. He's a bit uptight. But you see how skillful he is, and resourceful, and you understand his and Iris's relationship--it all makes sense in this episode."

Speaking of Iris, actress Candice Patton recently opened up to TVLine about her favorite on-screen pair. Patton, who plays Iris on "The Flash," revealed her admiration for Mulder and Scully of "The X-Files."

"I just think they have a really great partnership and dynamic. I love David Duchovny, and I love Gillian Anderson, I think they have a really great chemistry — and I'm one of those people who wishes they would just kiss already!" Patton shared. She would be happy to know that many fans of "The Flash" feel the same way about Barry and Iris.

Last month, Patton coyly told IGN a little bit about Earth-2 Iris and her relationship with Earth-2 Barry.

"What's nice is Barry, Iris and Joe, from what I can assume and tell just by being on the show, is they have a relationship that's so grounded it transcends time and Earth, and somehow they always seem to find each other on every timeline in every universe," Patton said.

Meanwhile, on the topic of crossovers, Patton shared that she would also love to have her character, Iris, crossover to "Supergirl" to interact with Calista Flockhart's Cat Grant, mostly to their journalistic similarities. Barry Allen is confirmed to be crossing over to "Supergirl," but fans will have to wait and see if any other characters will make their way into National City.

"The Flash" airs on Tuesdays, 8 p.m. on The CW.
