Best friends Barry (Grant Gustin) and Cisco (Carlos Valdes) will find themselves fighting over a girl in the upcoming episode of "The Flash."

In "Trajectory," the promo reveals that the boys of Team Flash cannot help but be captivated by the beautiful face of the speedster's newest foe. In the past, Barry has faced a lot of bad guys, including Zoom (Tony Todd) and, most recently, King Shark (David Hayter). This time, Central City will once again be the target of a villain determined to cause chaos. When The Flash checks in to see who dares disturb his city's peace, he will be stupefied to see that it is a woman.

Trajectory, as she is called, charms Barry with her smiling face and sexy body encased in a tight fitting speedster costume. Unfortunately for the superhero, she is not there to look for a possible date. Trajectory demonstrates her awesome speed and power as she knocks Barry around. Soon, he realizes that behind that pretty face is a foe who needs to be taken seriously. Still, while Barry's cuts are being treated at headquarters, he cannot get over the fact that he forgot to get her number.

Cisco is also hooked, as he looks excited over the match. He exclaims to the rest of the team that they finally have a female speedster after waiting for two years. The others are not so enthusiastic, especially the women. Caitlin (Danielle Panabaker) is seen gossiping that Barry went nuts while fighting with Trajectory.

Meanwhile, TV Line confirms that Eddie Thawne (Rick Cosnett) will be seen once again in the upcoming episode titled "Flash Back." It appears that Barry will travel back in time to seek the help of his former mentor Eobard (Matt Letscher) to find a way to become faster. In the process, he will run into Eddie, who died in season 1. Eddie was Iris' (Candice Patton) fiancé, but he killed himself to stop the Reverse Flash's evil plan.

"The Flash" season 2 episode 16 is scheduled to air on Tuesday, March 22, at 8 p.m. EST on The CW.
