Cisco Ramon has spent a lot of his time on the show helping Barry develop his powers, but the idea of him getting some of his own was very much teased last year by Harrison Wells. In short, he'd be becoming, like his comic book character, the superhero Vibe. That's started to happen already this season - he's even got the name sorted - as he has increasingly had strange visions of things that are happening. What's not entirely clear yet is just how far his powers extend, or how much control he has over them. The vision of Kendra Saunders recently indicated seeing into the future, but it could be that she's already Hawkgirl (which the crossover promos also suggest, but she could become the character within that episode). Going into the mid-season break, it'd be good to see him master a degree of control over those powers, leading him to become the fully-fledged Vibe in the second half of Season 2.
