I'm guessing he'll either magically become strong enough to find all of the rock pieces they need for the time machine, or anti-Quake the planet back together.

The longer this goes on, the more mad I get like "Where were the Avengers, to stop this ONE person from destroying the planet?" I'm trying to enjoy the show on it's own merit, but it's hard.

It sucks no one figured out that Robin was strong enough to see multiple realities at once, and that she never got enough training to decipher the difference.
