The Oracle watches as parts of the time-stream are being destroyed by H'el, while Superboy, Supergirl, and Superman try to prevent it. In the distant past H'el attempts to stab Kara with the Kryptonite shard she used on him, but she breaks free. Meanwhile, in the more recent past, Superman watches his mother tell his father that they are about to have a baby (him). Superboy and Kara from before she became Supergirl fight against the Eradicator, who Superboy sends to Smallville through a space-time portal. The H'el of two time periods merges, bringing Superboy and present-day Supergirl back together. Then Supergirl launches a final attack to destroy H'el.
