Here in Delulu Land
So this is how I see it: (sorry not sorry if it's trash) (also established relationship between the three already)
Nesta strolled into the dining room to have dinner, only to be met by the sight of her two (don't tell them) favorite Illirians. She would've been delighted- however, she was having kind of a shit day, part of which was because half her hair was burnt off (dont ask), so she just sat down and started shoveling food into her mouth while ignoring the others.
"Hey," said Cassian, the emotional support guide dog of the galaxy, "You alright?"
Azriel murmured, "What happened-"
Again, ONLY because she had a shifty day did she say
"Oh, go fuck yourselves."
Cassian and Azriel, the absolute ASSHOLES, stood up and FUCKING SALUTED. They yelled, "Sir, yes sir!" In their most sarcastic voices, and went off into another room, to presumably do exactly what she had told them.
What else was she supposed do do but laugh? (And then go hunt them down and deny them orgasms for an hour for that joke- I mean, it was only natural, right?)
