These last couple of episodes have been a lot of fun, with the trip to Earth-2 offering a lot of opportunities for the cast to cut loose and do something different, while offering up plenty of nods to the viewers, such as Earth-2's Deadshot being a terrible shot. It provided the show with an injection of momentum - some Velocity, if you will - that it really needed, and in particular has once again established Zoom as a credible threat, even if his motivations are still lacking. Now, though, they've got the characters who matter to the plot over to Earth-1 and closed all the breaches. Does this mean that we won't be getting to spend anymore time there? If so, that's a massive shame, because there's still lots of that Earth left to explore.
