The Flash's all new episode will feature Barry Allen moving on from Iris West and going out on multiple dates.

Episode 12 is titled, Crazy for You, and will air on February 3, 2015 on The CW.

The official synopsis reads as follows:

Caitlin (Danielle Panabaker) decides that she and Barry (Grant Gustin) need to move on from Ronnie (guest star Robbie Amell) and Iris (Candice Patton) and find new loves so she takes him for a night out at the local karaoke bar. Caitlin doesn't have any luck making a love connection but Barry meets Linda Park (guest star Malese Jow), a sports reporter for the Central City Picture News, and asks her out on a date. When Barry tells Iris he has a date, Iris is surprised by her reaction. Meanwhile, Cisco (Carlos Ramon) considers Hartley's (guest star Andy Mientus) dangerous offer and the team searches for Shawna (guest star Britne Oldford), a meta-human with teleportation powers, who just busted her boyfriend Clay (guest star Micah Parker) out of Iron Heights. When Henry (guest star John Wesley Shipps) snoops around in an attempt to help Joe (Jesse L. Martin) and Barry solve the crime, he ends up in the infirmary after getting roughed up by inmates

In the last episode, The Sound And The Fury, Hartley Rathaway (AKA Pied Piper) returned to S.T.A.R. Labs to expose Dr Wells' dark secret, and take revenge on him for becoming hearing impaired after the particle accelerator accident.

Pied Piper revealed that the doctor already knew that the particle accelerator could explode, and yet went ahead with the launch.

Executive producer Andrew Kreisberg told Tvline that the fans will get answers about Wells' mysterious plans by the end of Season 1.

Dr Wells' "endgame will happen this season," Kreisberg promised.

"Wells has a definitive plan. When you look back, you'll see he's had a definitive reason for doing all the things that he's done throughout the course of the season. We think it makes sense. Hopefully, you all will, too."

Barry's mentor is truly a villain despite some of the good he's done for the Flash.

"As secrets start to come out, how do you reconcile the Harrison Wells that we see in this episode, who's a friend and selfless and kind, with this monster?" Kreisberg teased.

"The only debate we had amongst ourselves was how long will the audience accept knowing he's the villain and having the rest of our characters not know, which is something we've been dealing with for the back half of the season. Are people going to feel like they're dumb for not realizing this? Part of what's keeping these next stream of episodes going is how good at hiding his villainy Wells is, and how strong Tom [Cavanagh]'s performance is," he added.
