With Trickster exposed, she attempts to escape from Wonder Woman, while Clark (of Earth 2) attends to Lois' wounds, while our Clark is still pretty damn confused. Wonder Woman manages to catch Trickster in her lasso, and thats where everyone first learns of Darkseid, who speaks of his soon to come arrival. Wonder Woman demands to know what Trickster is doing on their world, but she speaks of something else, telling them that the Batman of Earth 2 is hiding a great weapon, what looks to be a giant piece of kryptonite. Trickster manages to escape, followed by Clark of Earth 2 leaving to investigate, while Wonder Woman and our Clark follow behind.
Flash back to Earth 2 Clark and Bruce's childhood, and conveniently enough, a young Clark comes across a broken down luxury car, with both Alfred and Bruce inside. As Alfred attempts to fix the car, Clark asks Bruce if he wants to play baseball, but it turns out mini-Batman isn't that great at it, but he is good at martial arts, which he shows off to Clark. Jonathan Kent comes up to Alfred asking if he needs any help, but Alfred says he's fine, and the two men watch their boys play together, and ultimately the start of their friendship.
Both Superman and Wonder Woman find the crystal that Earth 2 Batman used on our Clark, and it turns out that it's not kryptonite after all, but a crystal that magnifies the radiation of a smaller piece of K, and now that Earth 2 Superman knows what to look for, he can use his vision to see that the NSA has a much larger crystal that they're guarding, so that's the next stop.
Back to the flashback, Bruce and Clark continue to play, and the Kents offer them dinner for the night. After they eat, Bruce and Clark go off again, while Alfred admits to Jonathan that he could have had the car fixed by now, but wanted to let Bruce be a normal kid for once, something Jonathan can sympathize with. Even back then, Bruce was very astute, and noticed that Clark was holding back his strength, and the two bond over the fact that they feel very different from everyone else.
As Clark, Clark and Diana head towards the giant crystal, Bruce and Bruce (god, this gets to be a pain in the ass to type out) intercept with a Kryptonite missile, which leads to Diana and our Clark turning on the Batplane. Our Batman and Superman start fighting, but Earth 2 Superman gets them to stop, telling them the grownups are talking. Turns out that while Bruce was told by Clark to prepare for the possibility of him losing control, Bruce didn't know about the big crystal, which could actually kill Superman, until recently, thus the missile to stop Clark from arriving to it.
Turns out that Trickster has been hitching a ride on Wonder Woman all along, and shows up, once again speaking of Darkseid's coming arrival, telling them that the weapon they aim to destroy is their only salvation. She transports the four to the weapon, and asks which of them will save their world and which of them will die.
