The Flash Season 2: 12 Big Questions After 'Escape From Earth-2'

6. Has Meeting Reverb Changed Cisco?

Welcome to Earth-2 gave us the great moment of Cisco meeting his villainous alter-ego, Reverb. Seeing the two Ciscos opposite each other was a lot of fun, but also it teased some big new powers for 'our' Cisco, and the potential he has to be something greater than he is already. In this week's instalment, that seems to have had quite the impact on him. Aside from one Elsa reference (someone had to make it, and it had to be Cisco) he's a lot more serious here, which is in part owning to the tone of the episode overall, but also a possible indication of what the future holds for him. Not in the sense that he'll stop being absolutely hilarious (hopefully not, anyway), but that once he's back on Earth-1 he'll be developing his powers more, and becoming something of a genuine hero.
