Lyla. I'm going to miss you. More than you can even imagine. You were my first friend. You accepted me without any question. Maybe because as Harbinger you saw something in me that's worthwhile... Now all I have to do is find that thing. I'll try as hard as I can not to disappoint you...

Synopsis for "The Supergirl from Krypton, Part 5 of 6: Traitor"
On Apokolips, Kara Zor-El has Superman at her mercy. Despite Superman's pleas, Darkseid orders her to finish him off. Kara throws him through the window of the throne room, into a fire-pit. At the coliseum, Granny Goodness orders Wonder Woman to surrender, or the Female Furies will kill Big Barda. Wonder Woman decides to play her own game and throws her lasso around Granny's neck, telling her to order the Furies to surrender, or be killed. At the armory, the Demon Dog that swallowed Batman has smoke coming from its mouth, when it suddenly lunges forward and dies. As Batman emerges from the beast's mouth, he commands the soldiers to give him their armor.
In the fire-pit, Kara attacks Superman. Superman realizes that she may be as strong as him, and unless he acts, she'll kill him. Reluctantly, Superman opens his belt buckle to reveal his trump card-- Lex Luthor's kryptonite ring. Putting it on, he knocks Kara unconscious, though it breaks his heart to do it.
At Darkseid's palace, Batman arrives, wearing the armor of the Dog Cavalry. The claws on the armor break against Darkseid's skin, but Batman reveals that he has used Barda's Mother Box to arm the Hellspores. Realizing what they'll do to Apokolips, Darkseid pounds Batman into the floor and then into the wall, demanding that he disarm the bombs. Batman will only do so if Darkseid releases Kara and gives his word not to kill or try to reclaim her. Realizing that Batman will not give in, Darkseid yields. He expresses admiration for Batman's ruthlessness, saying that Superman and Wonder Woman wouldn't have been able to do what he did. Kara is free to leave, while Superman and Wonder Woman both vow to hold him to the promise.
Returning to Themyscira, all the effects of the brainwashing are removed. Before Superman and Kara leave, Kara says goodbye to Harbinger at her memorial, and tells Batman that she remembers her mother's name, Allura. Later, at the Fortress of Solitude, Kara is trying on a new outfit--a Supergirl uniform. She admits that she isn't sure she has a right to wear it, and is still ashamed of what she did under Darkseid's thrall. Superman dismisses it, saying that Darkseid is corruptive by nature, and whatever evil she displayed was put into her by Darkseid.
Flying across the county, Superman and Supergirl arrive at the Kent farm, as Superman wants to introduce her to his parents. Seeing no sign of the Kents, Superman assumes they're in town, and decides to wait with Kara in the house. Before he opens the door, a massive fist punches through, sending Superman across the yard. Kara sees the attacker--Darkseid. The Dread Lord says that his promise was only with regards to Kara, and that Superman was not part of the bargain. Darkseid fires his Omega Beams at Superman, but Supergirl flies into the path of the beams. The beams strike Kara, and her body appears to dissolve into ash.
