Following a poster released earlier this week featuring Grant Gustin's Barry Allen in his full superhero attire, The CW has premiered yet another poster for The Flash, this time showcasing the nefarious Reverse Flash's full costume. As you know by now, Tom Cavanagh's Harrison Wells was revealed as the Reverse Flash earlier this season, the mysterious yellow-clad villain who killed Barry Allen's mother when he was just a child. The extended trailer that debuted this week teased that Barry is travelling back in time to find Reverse Flash in next week's episode "Out of Time".

Next week's "Out of Time" will also introduce fans to Mark Mardon aka The Weather Wizard (guest star Liam McIntyre), who appears in Central City intent on avenging his brother Clyde's death, and sets his sights on Joe (Jesse L. Martin), who shot Clyde. When Mardon attacks Joe and Barry (Grant Gustin), Barry is able to super-speed them to safety but Mardon gets away. Barry warns Joe not to go after a meta-human alone but Joe doesn't listen and ends up in grave danger. Meanwhile, Cisco (Carlos Valdes) looks into the night the team captured the Reverse Flash and realizes something doesn't add up and begins to wonder whether Joe was right about Dr. Wells (Tom Cavanagh).

Barry and Linda (guest star Malese Jow) end up on an awkward double date with Eddie (Rick Cosnett) and Iris (Candice Patton). Do you think Barry will finally learn that Harrison Wells is actually Reverse Flash in "Out of Time"? Will Barry finally get to avenge the death of his mother? Chime in with your thoughts below, and take a a look at the latest poster below.
