Booster Gold #17

Booster travels to about ten years ago where he observes his previous confrontation with Supernova and Jason Goldstein. Avoiding them, and seeking to ensure that Barry Allen becomes the Flash, Booster follows Barry to a museum, where he finds Chronos and the same sword he keeps running across. Their encounter is interrupted by the chronal being who joined Goldstar and Skeets on the Time Bubble, who takes the sword, leaving Booster to get Barry to his lab in time. That task accomplished, Booster recruits his earlier self to help him solve the mystery of the chronal being and the mystical sword.
