Move over, Scarlet Speedster, Iris West is taking over as the Flash.

As EW previously teased, Iris (Candice Patton) will be temporarily suiting up on The Flash — and now we know why!

In the upcoming March 13 episode, Team Flash confronts a new bus meta, Matthew (Leonardo Nam). Otherwise known as Melting Pot, the meta has the ability to swap people’s DNA. During a battle with the team, Matthew transfers Barry’s (Grant Gustin) super speed to Iris, giving her the powers of the Flash. Hence, when a new threat is unleashed on Central City, Barry must act as the team leader, while Iris takes over as a speedster in order to defeat their new foe.

The episode is aptly titled “Run, Iris, Run.”
