Plot
Rip detects another disturbance in the timestream centered on Coast City right before its destruction -- which happens to be where and when Michelle is encountering the Cyborg Superman. Theorizing that the earlier attempt to prevent Hank Henshaw from becoming the Cyborg Superman by another time traveler was really an attempt to save Coast City, and that that time traveler could be the cause of the new disturbance, Booster heads there. He finds the time traveler, Sondra Crain, and she tries to convince Booster to help her stop Henshaw, but they may be too late.
