‘The Flash Season 3’ UPDATE: [SPOILERS] Episode 4 ‘The New Rogues’ Captain Cold Is Back! Crossover Episode With ‘Legends Of Tomorrow’ Coming? [VIDEO]

"The Flash Season 3" just aired a surprising third episode. Episode 4 titled "The New Rogues" is due to be out soon and there is a lot to look forward to. Perhaps the most anticipated event this season is the return of Captain Cold and of course, the revelation of Caitlyn's secret.

Captain Cold (Wentworth Miller) will apparently make an appearance in "The Flash Season 3" Episode 4 for the first time after he was supposedly killed in the last season. How could Captain Cold be alive? "Maybe it will all make sense when you see how he was brought back," says EP Todd Helbing.

TV Line reported that actor Wentworth Miller revealed during the show's panel at the San Diego Comic-Con last July that Captain Cold will appear midseason in "Legends of Tomorrow" as a member of a new group of villains known as Legion of Doom. Captain Cold will brew trouble alongside Malcolm Merlyn / The Dark Archer (John Barrowman) Damien Darhk (Neal McDonough), and Eobard Thawne (Matt Letscher). Can we expect that there's going to be crossover episodes between "Arrow, "The Flash" and "Legends of Tomorrow"?

As usual, Caitlyn Snow (Danielle Panabaker) is in the spotlight. "The Flash Season 3" is going to introduce us to Caitlyn's mom, Dr. Tannhauser, and it will shed some light on the frosty relationship between Caitlin Snow and her mother, played by Susan Walters.

Apparently, Caitlyn visited her mother, a world-renowned biomedical researcher, to help her deal with her growing powers. Is she finally going to reveal her secret?

How cool is Jesse Quick's new costume? We'll get to see her in action alongside Barry Allen in "The Flash Season 3" Episode 4 fighting a new metahuman known as the "Mirror Master." The promo showed Barry being trapped inside the mirror and it seems as if it is Jesse's turn to save the day.
