Following the epic two-night crossover event between The Flash and Arrow this week, The CW Network has released new trailers for both shows' midseason finales, airing next week. The Flash trailer gives us a good look at the Reverse Flash, a.k.a. "The Man in the Yellow Suit", the man responsible for killing Barry Allen's (Grant Gustin) mother several years ago. While many fans believe that Reverse Flash is actually Detective Eddie Thawne (Rick Cosnett), since his surname matches up with his comic book counterpart Eobard Thawne, his identity on the show has yet to be revealed.

While we don't know for certain if Reverse Flash's identity will be unveiled, these scenes tease a massive showdown between Barry and his nemesis, along with flashback scenes featuring a young Barry and his mother. We also see Barry telling his father (John Wesley Shipp) that he has found the "man in the lightning." We'll have to wait until Tuesday, December 9 to find out if Barry will avenge his mother's death or not.

If that wasn't enough, we also have a trailer for Arrow's midseaon finale, "The Climb". This new footage gives us a brief glimpse at Oliver Queen (Stephen Amell) battling Ra's al Ghul (Matt Nable) on a snowy peak. We've already gotten a better look at Ra's in the photos that debuted yesterday, but you can take a look at Ra's in action below.
