"The Flash" returns this Tuesday, March 17, to begin a run of new episodes leading to the first season finale of the DC Comics-based TV series -- and based on a newly released two-minute sizzle reel, it'll be an eventful few weeks.

The clip, first shown this past Saturday during the "Arrow" and "The Flash" PaleyFest panel in Los Angeles, included, but is not limited to, new teases concerning Barry (Grant Gustin) and Iris' (Candice Patton) romantic future; Eddie (Rick Cosnett) punching Barry; Eddie seemingly shooting two cops; guest appearances from "Arrow" cast members Laurel/Black Canary (Katie Cassidy), Ray Palmer/the Atom (Brandon Routh) and Felicity (Emily Bett Rickards); Harrison Wells (Tom Cavanagh) showing the ability to be in two places at once and, oh yeah -- delivering the rather firm warning, "I promise you, Barry Allen, you will die."

"The Flash" airs Tuesday at 8 p.m. on The CW.
