In a new spoiler-filled trailer for "Grodd Lives," the upcoming episode of "The Flash," the Reverse Flash (Tom Cavanagh) sets Grodd (David Sobolov) on Team Flash in order to distract them from locating him.

The new preview reveals that Iris (Candice Patton) has uncovered Barry's (Grant Gustin) for herself. Now, she joins Barry, Cisco (Carlos Valdes), Caitlin (Danielle Panabaker) and her father Joe (Jesse L. Martin) in uncovering just what it is that the Reverse Flash is up to -- while hopefully rescuing Eddie (Rick Cosnett) in the process.

"The Flash" airs Tuesdays at 8 pm EST on The CW.
