Synopsis for "Come Back To Me - Part Three"
Diana calls out to the giant jaguar while its eating its meal and asks him how he came about the aircraft around his neck. He states that he found it in a tree but there was no one inside. he introduces himself as Odio and as the sun starts setting, warns her that in this place one either kills or be killed. Etta suggests they flee too if the giant jaguar is running away, but Diana suggests surveying the place from a safe spot. They soon come upon a group of Neanderthals armed with modern weapons and Diana tries to talk with them once they are spotted.
The Neanderthals attack Wonder Woman however and she destroys a gun held by one of them, causing them to run away. Etta and her however spot that one of them had a bag of the United States Air Force on their shoulder, with Diana deciding to follow them. As they come upon a cliff, they spot a highly advanced aircraft, whose existence should be impossible given the level of technology in their own time, inhabited by Neanderthals. Diana guesses it must have been on the island for some while and decides to investigate, telling Etta to hang back for her own safety.
As she tries talking to the Neanderthals and asking them about Steve, the tied-up Jonah Hex calls out to her and tells her how he was abducted by them while hunting for food. He alerts her about them pointing their weapons at her and states there’s no way to talk to them. As soon as Diana unties him, Hex starts attacking them and she joins the fight. After the Neanderthals run away, Hex retrieves his guns and informs her that Steve as well as two pilots with him headed to a place in the south, even though he warned them not to. Hex and Diana learn where they are from and he decides to guide her to the place where Steve went.
Synopsis for "Justice League - Part Five"
The heroes are recovering from the violent explosion caused by Darkseid upon his arrival in the last issue. Flash is the first to regain consciousness, and is horrified to see Darkseid destroy a military jet and its passenger with his Omega Beam. Superman awakes next, and Darkseid targets the two of them with another Omega Beam. Flash grabs Superman and begins to carry him to safety at super-speed, urging him to move it. When the heroes split up, the twin beams split up also, each beam targeting one of the heroes. As an evasive maneuver, Flash vibrates and passes through one of the demon-bots, causing the beam to destroy that robot instead of the Scarlet Speedster. As Flash catches his breath after this exhausting but successful maneuver, he looks up to see that Superman is not quite so lucky. Taking the full brunt of the Omega Beam, Superman is knocked out, although not destroyed; and is seen being carried away by one of the winged demon-bots. The other heroes are regaining consciousness now, as Flash shares the horrible news that Superman has been abducted. The heroes discuss interrogating Darkseid to find out why Superman was taken. Green Lantern springs into action and attacks Darkseid. His constructs are not effective against the god of Apokolips; but GL courageously keeps trying even while being on the receiving end of several vicious blows from Darkseid. When Green Lantern shows his determination to continue the battle, Darkseid lifts Hal by his right forearm and applies crushing force, causing the arm to break in a couple of places. Darkseid sends him flying with another punch, and then walks away as Hal struggles to recover and persist against all odds.
Batman attempts to deter Green Lantern from going up against Darkseid in his badly injured condition. Batman wants to gather the rest of the team and form a strategy. He criticizes Green Lantern for wanting to carry on the fight with a broken arm. In response, GL fashions a moveable cast with his ring, and says he is prepared to die if necessary.
Batman continues to ask Green Lantern why he is driven to press on in this futile attack. Batman implies that he understands Green Lantern well because they are very much alike. After Green Lantern rejects this notion, Batman pulls a very surprising maneuver. He removes his mask, introduces himself as Bruce Wayne, and tells a short version of his origin; explaining that he was driven to train for a life of fighting crime after witnessing the brutal death of his parents at the hand of a mugger when Bruce was ten years old.
Bruce asks Hal to regroup with the other heroes, keep them alive, and keep Darkseid busy until Batman returns. When Green Lantern asks where he is going, Batman responds that he is going to rescue Superman.
Batman stands in the open in plain sight with his arms outstretched in an apparently submissive gesture. It does not take long for one of the flying demon-bots to swoop down and carry Batman away.
Green Lantern does regroup with the other heroes, and helps pull them out of the rubble. He shares his plan, that they should go as a group and follow Darkseid, who was last seen heading into the city on foot. GL explains that the heroes should stay out of sight for the moment. When they find Darkseid, Green Lantern will act as a distraction to lure him out, so that the other heroes can attack. This was precisely the plan proposed by Aquaman last issue. Green Lantern gives Cyborg the option to stay behind, since he has not yet officially declared himself as a superhero, but Vic is eager to join the battle. The heroes head towards the heart of Metropolis, to meet up with Darkseid.
We follow Batman as he is carried to another portal created by a Boom Tube. As Batman steps through, he finds himself in an unlikely place; peering out over a hellish landscape. It appears that Batman has been transported to Darkseid’s home world, Apokolips.
