The Flash Season 2: 11 Big Questions We're Asking After 'Invincible'
4. What's Happening To Earth-2?
Although Cisco's vibes initially hint at Black Siren, by the episode's end it is showing something far worse: the total destruction of Earth-2. As in, it's literally splitting in half.
No doubt this has something (or everything) to do with Zoom, but that doesn't really explain just what is happening here. Is he himself actually causing it do split? Or is there some inter-dimensional mayhem that's causing it to implode?
If it is splitting and maybe destroyed, what does that mean for its future on the show? Obviously they can always venture to other parts of the multiverse, but what about things like Gorilla City? There's still plenty left to be explored with Earth-2, so are they really going to end it now?
