After the captivating events of Batman and Red Hood #21 (you know, the issue that hasn't come out yet... I hate when books do this) Jason is flying out of Ethiopia when his plan gets hijacked... Bane style, but jokes on the hijackers, Jason does some violent things to them off screen, and later both Roy and Kori are standing in the middle of a wrecked plane, wondering where the hell Jason actually is.
Roy and Kori ask the locals if they've seen Jason, or know anything of the All-Caste. Bringing up the All-Caste wasn't the best of ideas, as it causes the people to scatter, pretending not to understand them. it's not until an old woman approaches the two, until they realize why they're being ignored. The woman tells them that the entrance only opens up to those who have learned the All-Caste's ways, as if she was trying to convince them to give up. Luckily for Roy and Kori, Roy sat in on some of Jason's meditation, so he figures he knows enough to get the entrance to open... something that doesn't necessarily please the old woman, who is actually Essence in disguise.
Both Roy and Kori make their way, albeit slowly (mostly Roy's fault) through the heavy snow, eventually having to rest, despite how determined Roy is to find Jason. Roy figures that his time with both Jason and Kori has been the only thing to give his life meaning, thus his determination to find Jason, who has had it rough recently.
While the two sleep, Essence sneaks up on the two, but is confronted by the ghost of her mother, Ducra. Essence doesn't seem to be pleased that Ducra is seemingly allowing those two to find their way to the All-Caste, as she enters Roy's subconscious in an effort to "persuade" him to turn back.
Essence manifests in Roy's head as a real bad dream comprised of who I believe is Roy's father, Green Arrow, Killer Croc and Hugo Strange. Just telling him how he's a screw up, a drunk, etc. etc. But, surprisingly, Roy takes Jason's words about the All-Caste's teachings to heart, and uses it to sort of defeat his demons in the dream, which leads him to wake up with the knowledge of the All-Caste's location.
Kori flies Roy into the mountain we saw real early in the series, but it doesn't take long for the two to get surrounded by some serious monsters. The two fight off all they can, but monster gets close to taking a swipe at them, until Jason shows up, having stabbed the creature in the back...
Jason is acting a bit funny though. He has no recollection of who Roy or Kori are. Initially, they think someone had done something to Jason, but the mysterious S'aru shows up, and says that Jason had done it to himself.
We then see Jason confronting S'aru, sometime before Roy and Kori showed up, claiming he can't deal with all the pain in his life anymore. Every time he gets closer to getting away from it, something worse happens to him... So, S'aru offers up a solution... taking all of Jason's memories.
