The most popular DC show titled '[The Flash](series:1068303)' displayed confusions in the mid-season finale. The show returns back on January 20th, 2015 (Tuesday).
Episode 9 had much more twists than any other. One of the major is believed to be on the identity of The Reverse Flash. As per the comic series, we thought the reverse flash to be Eddie Thawne (supposed to be short for Eobard Thawne aka Professor Zoom), but the show ended clearing this confusion. All we are left with a list of questions regarding Dr. Wells and Eddie. One of the greatest super-villans in the Flash's Universe are supposed to be Eobard and Malcolm Thawne (Cobalt Blue), also the Rival.
All the speedsters are exact opposite of the Flash. The possibilities are that Professor Zoom or Eobard Thawne might be from the Eddie Thawne's family or Eddie from the future himself. There are plenty of reasons why Eddie can turn against Barry. The major one being Barry's relationship with Iris West. According to the Comics and the DC Movies, Iris West ends up with Barry Allen, so it is quiet possible that after losing Iris to Barry, Eddie must have turned against Barry Allen and the Reverse Flash returned from the future breaking time barrier to destroy Barry Allen. That's when Eddie faced his future for the first time. However, the next season, for sure has some serious answers to give.
