Oh man.
I'm really happy that this turned out so well for the family. I'm really glad that this turned out well. That amount of guilt can crush someone's psyche. Multiple peoples'. And yet, it's turned out okay - the guilt hasn't disappeared and likely never will, but it's been assuaged.
I won't say it's a perfect method of completing this mini-arc (I don't think there's any perfect method of doing so given the backstory), but it's amongst the best possible.
