so I'm re-listening to the GTN audiobook (as one does) and THIS time i caught that the first time Gideon goes to lunch (eating leaves with her fingers, running into Silas, etc.) she just... tucks a loaf of bread into her pockets to take back to her room for later? so possibly Harrow's drawer bread was a perfectly logical follow-up to finding bread in Gideon's pockets when she searches her for keys. she's just leaving food in a manner to which Gideon has become accustomed!
ALTOH MY GOD SHE DOES… (gtn ch 10)… and the Drawer Bread Incident didn’t happen until after Avulsion (gtn ch 21) where, very crucially, Harrow lost all her clothing to the entropy friend and had to put Gideon’s robe on in order to walk back to their rooms…. you know what I cannot blame Harrow at all for making the leap that if Gideon had bread in her pockets she would probably be okay if Harrow put it away for her. she was doing her a courtesy like
imagine almost dying in some kind of nefarious escape room type trial that relied on you almost (actually) killing your teammate/ servant/ enemy/ longtime crush/ complicated situationship via soul suck and losing all your clothes in the process, thereby causing her to see you nude before dying because you sucked her soul too hard. luckily, she revives, and you steal her overcloak to cover yourself and find it is for some reason full of bread, which you helpfully leave with her in a more accessible location after dragging her all the way back to your room….
