Sad for the little girl and probably terrifying for her and her family, whatever the actual cause.

I agree, there's no way the mask just imploded in the pool, she probably tripped, hit it on the bottom, side , ladder or something. Having said that, I'm sure the lawyer is working on a percentage of the settlement basis so he asks for nearly $800k with the full expectation that the company will pay something rather than have to pay their own lawyers to fight it. A lot cheaper to settle than to go through the legal process, even if they would ultimately win.

My guess, they'll settle for medical costs + $20k or $30k and the lawyer will get 10 or 15 grand for writing a couple of letters. I believe the technical term is "Ambulance Chaser".
