Hello, this is Mom Universe. The children are playing swords. Sorry, playing with swords. They are bleeding. Oh no, they are dead. Never call here again.

Sorry, I panicked

ah. I suppose that certainly didn't help the situation (along with the bit about randomly finding it, which implies huge irresponsibility)

If they had just said that Pearl was a fencing instructor, and that it was his mother's sword, it would have most likely gone a WHOLE lot better. Hell. they might have been able to work it into the 'schedule'. Fencing is cool, and actual sport and all.
