"The Flash" season 2 will finally introduce Reverse-Flash, Killer Frost, Earth-Two Barry and Iris in one of its upcoming episodes.
In the show's upcoming 11th episode, Matt Letscher's Eobard Thawne or Reverse-Flash will return to the hit The CW series.
"The Reverse-Flash Returns" will focus on Reverse-Flash putting the lives of the members of S.T.A.R. Labs in danger.
According to executive producer Todd Helbing, Barry (Grant Gustin) would also have to make a difficult in the said episode.
"His impossible return to Central City puts a member of the S.T.A.R. Labs team in unexpected danger, forcing Barry to make a life-changing decision," the episode synopsis read.
According to Design N Trend, it is still unclear what life-changing decision would Barry have to do, and how it will affect the rest of the episodes for "The Flash" season 2.
Meanwhile, Barry will also meet the Earth-Two version of himself, Iris (Candice Patton) and Caitlin or Killer Frost (Danielle Panabaker).
One of the photos that leaked online showed Barry's Earth-Two version wearing eyeglasses. Some fans believe that Barry could be working as a television news reporter.
Twitter user @yvrshoots shared a photo and wrote, "Barry Allen as we've never seen him before #TheFlash at #Vancouver's Queen Elizabeth Theatre."
Another leaked photo showed Barry and Killer Frost engaging in a fight scene.
"Killer Frost not a fans of Barry Allen 2.0. #TheFlash filming in downtown #Vancouver tonight," the same Twitter user wrote.
"The Flash" season 2 is currently on a short hiatus. The series will return to The CW on Jan. 19, 2016 at 8 p.m. ET.
