Tonight's new "Flash" episode will see Barry and Cisco by Dr. Wells' side as he travels back home to Earth-2 on a mission to rescue his daughter from the clutches of the evil Zoom. Despite the dire straits and high stakes, "Welcome to Earth-2" will feature plenty of alternate reality fun -- as revealed in these new clips.

TV Insider and Collider have posted scenes from tonight's adventure that show off different sides of Earth-2. In the first one, the villainous versions of Flash allies Caitlin Snow (Danielle Panabaker) and Ronnie Raymond (Robbie Amell) make their mark on a few criminals.

The second clip depicts a meeting of two minds, both of which belong to Barry Allen. Well, two Barry Allens.

Additionally, the CW has released an inside look at the episode, which includes comments from executive producers Todd and Aaron Helbing and further looks at the cast's Earth-2 counterparts.

"The Flash's" "Welcome to Earth-2" airs tonight on the CW at 8 PM ET.
