GRIDDLEHARK AND CAMPAL ARE OPPOSITES BUT ALSO PARALLEL TO EACH OTHER AND IT MAKES ME SO INSANE
6th House is on mercury and 9th House is on pluto so they're on the opposite ends of the dominicus system
9 is 6 uspide down and 6 is 9 upside down
the Ninth House and the Sixth House are religion vs science
Gideon and Harrow are (were) childhood enemies, Camilla and Palamedes are (were) childhood friends. Gideon and Harrow had a hard time trusting each other, Camilla and Palamedes trusted each other with everything.
Gideon and Harrow are all about forgetting ("But I don’t even remember about you most of the time", the whole lobotomy situation), Camilla and Palamedes are all about remembering ("I’ve carried you, Warden. And I’ve carried your memory … I’d rather carry you", "Palamedes remembers everything: That was his problem. I always remember him. That’s mine")
Gideon and Harrow are water (the Pool Scene, Gideon being in the "well" in Harrow's mind, Harrow deciding to stay in the River and Gideon "dying" in the River), Camilla and Palamedes are fire (Palamedes's first death, Palamedes and Camilla's lyctoral ascention)
in griddlehark's case the necromancer carried their cavalier's soul, in campal's case the cavalier carried their necromancer's soul
Gideon and Palamedes sacrificed themselves, Harrow then carried Gideon's sword even though it was killing her and Camilla carried Palamedes's bones even though boe electrocuted her for it
Gideon and Camilla are both "devotion's casualties"
Harrow and Camilla risked permanent brain damage to save the souls they carried
Gideon barely had any training for her position and Camilla trained her whole life, but they both didn't normally use their rapiers and were both set on fighting rather than on traditional duelling
the 6th and the 9th are both poor, underestimated, dying houses. Harrow and Palamedes have been leading them since they were very young and they do anything to try to improve the situation
Harrow fell in love with the Body when she was 10, Palamedes began writing to Dulcinea when he was 8. both into old dead chicks (as Gideon phrased it) while also loving their cavaliers
Camilla watched Gideon impale herself to force Harrow's ascention, Gideon watched Camilla light herself on fire during her and Palamedes's ascention
"This was your shell but it was all filled up with me" & "It's not you. It's me wearing you"
"I keep turning around to find you, and there’s nobody there." "I know the feeling." & "You’d touched that letter, and I—you know it was killing me twice that you weren’t there, right? You must know it was destroying me to be there in your body, trying to keep your thumbs on, and I couldn’t even hear your damn voice?"
"Kiriona Gaia was staring politely at the side of the truck, as though there were something really interesting on the paintwork" & "Even Camilla, who had turned away to politely investigate something on the opposite wall, wasn’t there"
"It was just her and Harrow and Harrow’s bitter, high-boned, stupid little face" & "Palamedes said, and now Nona knew he wasn’t speaking to anyone else in the universe"
there's probably more, that's just from the top of my head. but yeah, they make me insane and i'm foaming at the mouth.
EDIT: of course there's more
Palamedes and Harrow were both stuck in river bubbles in htn
"Oh, never mind. She knows what to do." & "You’ll know what to do, and if you don’t do it, what I’m about to do will be no use to anyone."
"But for the love of the Emperor, Griddle, you are something else with that sword." & "I love the way she moves,” she said pitifully. He said, “Me too."
"Like, at the end of everything, if it was going to be you and me, layered over each other as we always were. A final blurring of the edges between us, like water spilt over ink outlines. Melted steel. Mingled blood. Harrowhark-and-Gideon, Gideon-and-Harrowhark at last." <- sounds familiar, doesn't it? you could replace Harrowhark-and-Gideon with Camilla-and-Palamedes and it would still fit perfectly
"What about Camilla Hect, the independent entity? Free to live her life outside the shadow of her necromancer? Free from his agenda dictating hers?" <- same situation, it fits perfectly for griddlehark
"Now—first make sure nothing’s going to ice Camilla—I meant it about not wanting an afterlife subscription to Palamedes Sextus’s Top Nerd Facts." & "And yet if I don’t preserve her…Ninth, really, I sincerely did not want to have to look after your bedamned water bottle."
