The Flash Vol. 2 (1987-2006) #225

Plot

Barry takes Professor Zoom back to his proper time period. Zoom and Wally return to the moment when Zoom caused Linda's miscarriage, but Wally subtly changes the events of that day. Zoom tries to use the Cosmic Treadmill against Wally without Professor Zoom, but since he is fueled by time, not the speed force, the treadmill explodes, taking Zoom with it. As the survivors take stock of their lives, the effects of Wally's efforts in the past take hold with happy results.
