That's when green takes cover for her actions, as the author have implied that everyone lives different in their lives, that applies to the short hair girl. You must have noticed how the difference of each "Edith's" has acted, most cause their "greed" and that basically sums up that she's probably one of those people that rather want to enjoy the suffering of others and use the excuse that she was a victim, just the author(on the novel) did, basically the author is getting a taste back of what the other Edith's experienced, it's just the shorthair girl was pushing it more due to her greed ╮( ̄▽ ̄)╭

I think the ending for the author and cliff was alright, but why is that girl with the short hair so obsessed to see them suffer? As if she doesn't want to see herself with a new life but rather stay there to see them, people she hated, suffer? I think it's a better choice to be able to live her life a new since she's already punished them
