Spoiler!
This is the arc when she starts questioning herself and has a lot of inner monologues, also she feels like she created a monster. Ann and Muen fight against Elka together in the WN
in the WN, Ann is initially really impressed and sort of taking notes of potential se** time stuff. But she slowly starts to question Elka's methods the longer she looks at her “husband”. She sees the lifelessness and lack of emotion, and wonders what's the point if they don't have life or emotions in the eyes to reciprocate the feelings back. She starts getting creeped out.
