So “the girl Legionnaires” all come down with a fever which turns their skin crimson. What else it does isn’t really specified, but the illness is apparently fatal, and Superboy, of all people, tells the girls they’re doomed and have to go to the quarantine world. Not really Superboy’s style, telling people they’re just gonna die.
Phantom Girl is back in this issue, but doesn’t say a word. She turns red and sits in a wheelchair. Readers who missed her one appearance years back don’t even have any idea why she’s called “Phantom Girl.”
The remaining (male) Legionnaires are taunted by the arrival to Satan Girl, who has the power of a Kryptonian on Earth, and brashly demands Legion membership. When the boys pretty much say, “Uh, waitaminute…” she announces that she caused the Crimson sickness, and now she’s going to kill all the female Legionnaires.
