Hey! I hope my assumption about Della and Grimmjow's interactions (since they're roommates) before the Halloween party is okay. If not, let me know and I'll be happy to edit.
Okay, great! And likewise I know... nothing about Della except. You know. She's a duck. As for what she should know, it's probably pretty obvious that Grimmjow is new to food in general. And if she's particularly perceptive, she could have picked up on his illiteracy/the fact that he's trying to secretly teach himself to read/write.
As for Della, aside from duckness - one of her legs has a prosthetic made out of rocket ship parts. Personality-wise, she may have tried bugging him for questions/deets about himself, but if he refused to divulge, she would've given up for now.
But also if anyone ever tells him people eat duck he's gonna pout about not being "allowed" to eat her. (His previous diet was souls, so like... all the passengers are food to him.)
Oh! I also forgot. Grimmjow has a sword and he doesn't go anywhere without it, but he doesn't unsheathe it very often. Relevant to the tag I'm writing now lol
Grimmjow is gooey on the inside if you can get that far. Della can almost certainly get that far, he doesn't know how to handle that kind of Powerful Optimism.
