Emily
Emily Bright, I'm going to say this one last time and then I don't want to hear an apology from you again.
You made a mistake. It was not in any way intentional and you and Albus had no idea something could go wrong from a seemingly simple spell. You're young, you're still very much learning, and no one could have expected you to know what to do in a dangerous situation like that.
America and Christine don't blame you and neither do I. And it's time for you to stop blaming yourself.
