Booster Gold #21

After an encounter with the Black Beetle at Vanishing Point, Rip decides that Booster needs to do a better job of covering his tracks. He sends Booster to the Batcave to retrieve the file on Booster kept by the Batman, the only person who knows that Booster protects the timeline. But there, Booster encounters the new Batman, Dick Grayson. While Booster tries to explain the situation to Grayson, the Black Beetle appears. Deciding he would rather there not be a Batman, the Black Beetle leaves, and suddenly Grayson is gone and a second memorial Robin costume is on display in the Batcave.
