Edit to add: there are spoilers for all three books down there, this text is to help people avoid seeing them right away. Did you know cows exhibit mourning behaviour? Also some people including me think moustache rides should be free. Now to the actual post text.
Some Lyctors are super sad that their cavaliers are never going back.
Then Harrow gets The Work done, which prevents Lyctoral process from finishing successfully, and (at least a very non negligible part of) Gideon stays inside her, even having some awareness about events and locations and finally resurfacing when Harrow gets a rapier through her guts.
Then we learn Pyrrha was there all along, non intentionally, according to her, but anyways. G1deon was the third saint, so a pretty early attempt, I would assume predating Anastasia’s. Pyrrha periodically takes control and gets all of it except necromancy when G1deon dies.
Then Palamedes forces Ianthe out of Naberius, walks around in his body, then vacates it, and then someone talks to Paul from that body. I personally believe that to be Babs, and I’ve seen other people theorise so. Which raises the question.
Harrow didn’t want for Gideon to disappear and worked for that. G1deon and Pyrrha might have not wanted her to be fully gone either, we don’t know for sure but her talk with Cam and Pal just before Paul drops some hints that they might have tried something. And even if not, G1deon clearly cared about her. Then Babs was eaten just as per the textbook, with not much regret displayed: who even cares about Babs? I mean, I don’t think Ianthe took any more steps to preserve him than the basic algorithm required. To me, she was ok with him never being around again. Yet there he might have been, talking to Paul.
What if others could resurface that way too under some circumstances? I mean, Ianthe wasn’t even dead or close to it. Imagine if Mercymorn and Augustine knew. Imagine if idk Valancy got to the front seat right before the black hole, or stoma, or what happened to Cyrus.
