The Flash Vol. 2 (1987-2006) #200

Plot

As Zoom tries to teach Flash about loss, he also open visions of significant moments of the past, including one which upsets him so much he flees. While Wally has a moment, he confers with the other speedsters, and Jay theorizes that Zoom has not tapped into the speed force, but into time itself. Taking the speed force from all the other speedsters, Wally is able to meet Zoom on his level, and traps him in one of Zoom's windows on the past. Finally, as Wally takes stock of the recent events of his life, he is visited by two old friends, and all knowledge of his dual identity is wiped away.
