Time travel also makes my head hurt. But it’s a nice touch that Blue Beetle Ted Kord was able to travel in time before his death to be with his best friend Booster Gold in his dying moments. When Ted Kord died a few issues ago, Booster Gold also stayed with his friend til the end.
Booster Gold sacrifices his life in order to save the new Blue Beetle Jaime Reyes, who gave up his scarab in order to stop Red Lantern Starro.
