The Flash midseason finale "The Man in the Yellow Suit" concluded with a significant reveal: Dr. Harrison Wells (Tom Cavanagh) in possession of the Reverse-Flash costume - which obviously seemed to indicate he was in fact Reverse-Flash. Of course many of us felt that there must be more to the story. Sure it had been clear that Wells was up to something, what with the walking around, looking into the future, manipulating the present, and apparent ruthless disregard for human life of it all. Yet, as the biggest bad that Barry would face -- and given Eddie Thawne's (Rick Cosnett) role in the comics as Professor Zoom/Reverse-Flash -- it seemed impossible that the series would offer up as simple an answer as Wells' reveal as the villain.

"Yes, I am Reverse-Flash," the actor confirmed. Case closed, right? Not quite yet.It looks like there may be a possibility of more than one Reverse-Flash - and/or the show could be introducing Professor Zoom as a separate character. When asked for clarification on Eddie's role in the show, executive producer Andrew Kreisberg said, "Rick Cosnett very amazingly plays Eddie Thawne. And his name is not an accident. That is going to pay off big time in the back half of the year."IGN was able to catch up with Kreisberg following the panel to ask for clarification."Eddie has a strong connection to the Reverse-Flash," the producer said. "I don't want to spoil anything, but you're going to start to get the gist of it pretty early on. In episode 15, you get a pretty big clue."He added, "Episode nine really changed everything. Some of the things, like Barry telling Iris he loved her -- obviously that's going to change their lives -- but there are things that happen in nine where even the characters don't realize how much is about to change. There is obviously a big surprise regarding Tom's character, but there are even more surprises to come."Yet, he seems almost obsessively focused on helping Barry to reach his full potential."He obviously wants something from Barry," Kreisberg told IGN when asked if Wells is motivated by a desire to see Barry become The Flash at any cost. "What that is is part of the big surprise in the back half of the year. But it's what makes writing him the most fun. He's always put in a position of, 'Is what I'm about to do or are my actions going to further my own agenda, or is it for the greater good and helping the city?' So I think that's why Tom has so much fun playing the character and why we have so much fun writing the character. Like he said, everything he does, there are two agendas, and making sure that everyone else's agenda doesn't override his own. That's his chief job.""Joe and Cisco are actually going to launch an investigation into what really happened that night," Kreisberg told IGN. "It's funny, every couple of episodes you get a giant piece of the puzzle. So hopefully people won't feel like we're dragging it out for too long. We watched a cut the other day, and Greg and I were both like, 'Oh my God, I forgot that happens in episode 13!' So yeah, we are definitely going to find out what happened that night. What's fun is, we're going to keep seeing that event from lots of people's points of view."There were other people there that night," the producer continued. "There was Barry's mother, Barry's father, the two Speedsters. So getting to see that night from different perspectives, it's funny, because the actors keep coming back, and they have to keep playing the scene over and over again but in slightly different ways. We see things that we didn't see the first time, or we see things leading up to it or the aftermath. So that event is obviously the seminal event in the history of the series. But you'll definitely get the answers."Adding fuel to the "multiple Reverse-Flash" fire, Kreisberg told EW that, “We’re going to see what happened that night from the Reverse-Flash’s point of view."Yet when asked if that meant Wells, he clarified, "I didn’t say it was from Wells’ point of view, I said it was from the Reverse-Flash’s point of view.”One key ingredient to this story is the existence of time travel. When a reporter asked how it will appear in this world, Kreisberg said, "Definitely by accident. There's an unexpected, accidental time travel coming up, that is played for both hilarity and darkness. It happens in an episode we're really excited about. It's the first Weather Wizard episode with Liam McIntyre."We will keep you updated as details emerge.
