I mentioned a few weeks ago that one of my early-2016 hopes was to see The Flash take its second season on the (inter-dimensional) road.  This preview gives a nice peek at what’s about to happen on The Flash:

There’s geek-talk, of course, about the identity of Zoom, the season’s big bad (who doesn’t have much presence in this trailer).  There’s also some speculation about how much this Earth-2 might resemble some other of DC Comics’ infinite earths.  Good to know we’re closer and closer to Barry breaking the dimensional barrier. (Will there be a cosmic treadmill involved?)
