Some things just cross the line.
She didnt expect that Syril would have any other reaction to the ghorman genocide than submission.
I find myself thinking that this situation is the first time she actually “lost”.
I mean she actually lost at Ferrix and with not finding Axis. But yeah Syril was like the first non-fascism/work related relationship she had. Her apartment is sterile, empty and just exist too keep her alive until she can go to work again. She is completely devoid of personhood.
The dinner scene also shows, that she integrated syril neatly into her world (they both wear black & white), while syril’s mom is a disruptive force in her world, symbolized by her garish hérmes-bag inspired orange clothes.
