At first I wanted her to play with it, but I wanted her to be a virgin so I decided against it, and then I just forgot about the arm. And I felt a bit bad for Aigis while writing this part – she loves the player’s character in game canonically, and with the setup in part 1 she couldn’t get a happy ending. One might argue that her suffering makes her death all the hotter though.
As for Margaret and Elizabeth – they’re incredibly powerful, so dying isn’t that much of a deal for them. I think you’ll like the way I’m writing Margaret. Thanks for replying!
