Flash of Two Worlds concluded with giving us a look at Earth-2s Harrison Wells, and Family of Rogues followed suit by doing the exact same thing. Only this time Wells was actually in our world. Thanks to the Speed Cannon, this episode comes to a close with Wells stepping through the two worlds and showing up in Earth-1, bringing with him plenty of dropped jaws and a whole host of questions. Clearly the Earth-2 Wells is in tune with travelling between worlds, but does that necessarily mean that hes Zoom? Could he be another speedster? Could he just be a genius mind who is exploring the notion of parallel worlds? And just how is Barry Allen going to react to see the face of the man who killed his mother (even if he technically had a different face when that happened) and who was last seen being removed from existence be Eddie Thawne sacrificing himself? Sure, many expected some sort of follow-on from last weeks Wells appearance, but nobody expected him to rear his head in Earth-1 just yet.
