The Flash season 2 new trailer

They say blondes have more fun, but in the latest teaser trailer for The Flash season 2, Caitlin Snow decides she’d prefer the dark side.

“It’s so much more fun to be bad,” Caitlin, played by Danielle Panabaker, declares in the clip. The teaser also shows Barry (Grant Gustin), a.k.a. the Flash, taking on Reverse-Flash, who EW revealed will be played by Matt Letscher when he returns to Central City in the upcoming season.

When we left Reverse-Flash (non-villian name: Eobard Thawne), he’d gotten stuck in the past after traveling back in time to kill Barry’s mom. So in addition to defending his title as the “fastest man alive,” it’s safe to say Barry will have another bone to pick with Eobard.

Check out the latest teaser, above, to see things in Central City take a turn for the worst.

The Flash returns to The CW on Jan. 19.
