After the Downer Ending of issue 23, issue 24 ends on a happy note. Supergirl's body is restored, her kryptonite poisoning is removed, the entire collective of I'noxia is safe from Brainiac, and they escape Cyborg Superman's grasp. The collective thanks Supergirl for sharing her memories with them and remind her that her familiy's love is why she's alive. Before they part ways, they tell her to find happiness, because the search for it will truly lead her home.
