LBDJVSK don't worry Otegine will be able to tell, he has the ability to sense when spiritual types are around him to an extent so he'll likely just assume childe's just a really bloodthirsty human.

TALKING ABOUT STRENGTH... yeah even coming at it from what he remembers about his masters and who he considers to have a lot of strength, it's definitely gonna be a different take than mister "I fell into the abyss and all I got were these dead fish eyes" (I love childe i promise) so I look forward to if that comes up! Morality in general is always interesting for swords anyway since they can and will commit some pretty massive slaughter if it means keeping timelines in order, just how they personally feel about it can vary. u_u
