Tier made one promise to Junco. Save House. So that's what Tier does. He picks up the AI, takes her to Gideon's island, and does his best to come to come to terms of what Junco did. But House has secrets of her own and Tier, Hand, and Annun are on a mission to figure them out. They have to. Because she's dying. And if she dies... She can't die. She just can't.
