With the three Legionnaires free and Doctor R'Xalim captured by the Science Police, Brainiac 5 and Element Lad head home with Matter-Eater Lad in tow, in hopes that Brainiac 5 can cure him.
We see Chameleon Boy's finally come to terms with the gravity of the situation he and his teammates are in, and how his rash behavior is ultimately what's responsible for the death that surely awaits himself and his four comrades. Luckily for him, their ship-wrecked crew is rescued by Dawnstar and Lightning Lass, but I anticipate, that like Lightning Lad, he's got more trouble on his horizon as well when they return to earth. And of course Star Boy continues providing some comedy relief with his absolutely awful, inconsiderate, pessimistic comments about the state of his lost teammates. What a jerk.
And of course the biggest plot moment of the issue outside of the lost Legionnaires being located by Dawnstar and Lightning Lass, is Darkseid! We see him unleash his forces on an unsuspecting and unprepared, 30th Century. In the story his true identity is still hidden in shadow, but come on he's all over the front and back cover of the trade paperback, so obviously it's him!
