This part is supremely uncomfortable, and it's meant to be, I think. Laios isn't defending himself here, this is murder, premediatated, and it's one of the worst ways to kill someone too.
Made all the more twisted by how he tenderly ruffles Falin's hair, a very common anime-older-sibling gesture, usually a comforting and protective I-love-you, you-did-good type thing, and how she looks up at him, dazed and completely vulnerable, only for him to immediately turn to violence before she can even think of defending herself.
There's also a terrible intimacy to the part where he suffocates her, it sincerely does make me very uncomfortable, it feels sick, and I think it's on purpose. It's a terrible way to die, Laios has to basically wrap himself around Falin to do it, see every little way he's hurting her. His sister always trusted him so much, and he always wanted to protect her, but now he's making her suffer. It's in service of eventually saving her.
Out of the party, the one Falin Chimera injures the most (or at all? possibly?) is Laios, and I think there's significance to that. She's spent so much of her life taking care of him, following him, putting his needs above her own. But as Chimera Falin, she lashes out, she shows anger for the first time, and she struggles against him. How much of that is dragon mind control, and how much of that comes from an unrestrained Falin? Does it feel good to finally fight for herself, to not be the sweet little sister, but a threat? Does some part of Falin who spent her life wanting to please others, enjoy the power, enjoy the violence? Hard to know.
There's also the question of, if they do bring Falin back to life, will she remember this? Will she remember her brother killing her? That'd be really fucked up.
LAIOS will definitely never forget.
Meanwhile, Marcille can't even bring herself to look. She covers her eyes, closes her ears. Doing nothing as Falin dies is killing her, and all she can do is try to block it out.
