You have absolutely nothing to apologize for! I'm only relieved you're okay. However, what do you need the skelegrow for? How severe were your breaks? The hospital is a much safer place to be than the castle for explosion type injuries. They'll release you only once ensuring that you'll be okay.

We can send letters all throughout the days if that'll help with your boredom. Have they informed you what caused the explosion yet? I was two streets over when it happened, but you could hear it all the way to London I'm sure. (Speaking of hearing, have they examined yours? Will you have any long lasting injuries?)
