Title: Flash (Barry Allen)
Content:  Wally West, wracked by grief for the loss of his unborn twins at the hands of Zoom, regrets the public knowledge of his identity. Barry appears from somewhere in time—stating that he is from a period shortly before his death—counseling his nephew, and talking the Spectre into granting his wish, erasing all public knowledge of Wally and Barry's identities as the Flash (Although Wally himself also loses his memory of his identity for a time). Barry then disappears, telling his nephew that he will come to his aid three times, on the three most difficult days of his life of which this is the first. In fact, when Zoom enlists the aid of the original Professor Zoom to make Wally relive the loss of his beloved twins, Barry is already there, trying to stop his "own" Reverse-Flash; Zoom apparently retrieved Eobard Thawne from the day that he attempted to kill Fiona Webb, with Barry following his nemesis. For the second time, he helps Wally to undo the damage dealt by Zoom, also allowing Wally to save his twins, and then he returns to his proper time, dragging his Zoom with him and breaking his enemy's neck in his timeline.
