Bart Allen is utterly depressed about losing his best friend--so much so, that he wants to give up being Impulse. However, first he needs to contend with this new power of his and the reappearance of his old foe White Lightning.

Bart mourns on the loss of Carol's prescence, Bart exhibits his ability to create duplicates of himself through the speed force, and Bart has a talk with Max while running around the world.
