On the topic of travelling between Earths, if all the breaches have now been closed, and Team Flash can't get to Earth-2, then what does that mean for Zoom coming to Earth-1? Barry had previously insisted he wouldn't just close the breaches and leave Zoom to run riot on the other Earth, but that's what they have now done. As for Zoom, he's obsessed with getting the Flash's speed, so he needs to get back to Earth-1. Will he still have another way in, or could they perhaps re-open a breach?
