Well, it's finally over...

Not much actually happens in the story. Jason has tricked the Dark Gods due to his ridiculously overpowered "can-use-any-god-ability" outfit. He pretends that he's under their influence, and tricks them into entering Diana's unconscious body (he put her to sleep using Morpheus's god powers; she was willing obviously). There, they try to battle the Dark Gods, but then Jason comes up with an idea. He offers himself to King Best in exchange for returning the Justice League and leaving this plane of existence, returning to the dark multiverse. King Best for whatever reason decides this is a good idea and Jason says his goodbyes to Diana and vanishes. All the while, Diana talks to Steve about it in standard Robinson dialogue.

The most important takeaway? Diana doesn't like Steve's beard because it hurts when they kiss.

So yeah... no big ultimate battle with the Dark Gods. They were so supremely bland that I really honestly hope we never see them again. As for Jason... we all hoped this would happen so, yay? He's not six feet under but I don't think he'll return anytime soon.
