Cisco (Carlos Valdes) found out in "The Flash" Season 1 finale that he has super powers; his visions of his own death are happening because of the effects of the particle accelerator.
While a person as excitable as Cisco might be excited that to find out they have time-bending abilities, the circumstances surrounding his discovery are going to cause some problems in Season 2. Dr. Harrison Wells (Tom Cavanagh) was the person who told him about the super powers, but Wells was also the person who killed Cisco in an alternative timeline, thus causing the visions. That's a traumatic start to any heroic destiny.
"Cisco, at this point, is so overwhelmed with all of the madness that’s going on: Barry going back in time and [Cisco] possibly losing him as a friend and changing the reality and the timeline. On top of that Dr. Wells [tells] him about this fate and destiny that the’s supposed to have," Valdes explains to Zap2it at San Diego Comic-Con.
Cisco is going to have to find a way to deal with all the "madness," though. Season 1 ends with a giant wormhole open above Central City, and his body is already starting to change and his powers are starting to kick in.
"There are changes to Cisco’s biology that are happening. With the whole dream sequence that was covered in episode  and other episodes as well — that’s a primary part of the changes that are going on with his body. You can definitely expect pretty early on for Cisco to start grappling with those changes," Valdes says.
Because of the way Cisco was introduced to his powers, he won't have as fun becoming his superhero identity, Vibe, a Barry did becoming the Flash -- and it may inhibit his work with the team.
"It’s very overwhelming. He’s in a complete state of denial," Valdes says. "That denial brings about a bewilderment that he’s victim to."
