I can change it? Even someone like me can do something to help? Can I really change how this ends?

Sayaka, you can't fight like that. You're lying if you say it doesn't hurt. It hurts just watching you, just because you can't feel the pain doesn't mean it's okay to hurt yourself.

It's better this way. I want you to do something that I couldn't do. You
can go back in time, right Homura? You can go back and change
everything, so that we don't end up like this.
