In "Escape from Earth-2," the next episode of "The Flash," Barry is trapped in Zoom's clutches -- but he's not alone. With help from Harrison Wells' daughter Jesse, he figures out how to communicate with the mysterious man with the metal mask who occupies the cell next to them.

The CW has also confirmed to ComicBook.com that an earlier trailer offered fans their first glimpse of Allison Paige's Trajectory, who will debut in episode 16. After she stirs up some trouble in Central City, Barry gets the blame, which drives him to find her and stop her before she completely ruins his reputation.

Starring Grant Gustin, Carlos Valdes and Jesse L. Martin, "The Flash" returns airs Tuesdays at 8 pm EST on The CW.
