Pinging a few names to this thread in case you haven’t seen it.
Don’t all hearts get irregular when the person dies?
I posted a fuzzy screencap of what looks like Fuddy floating pale faced and obviously very un-alive before she was picked up by the rescue team. To the people who want to know why Yamamoto didn’t keep hold of her I would say, would you hang onto a dead woman for an hour in choppy water knowing that it’s impossible to try to revive her while treading water?
If I wanted to silence Fuddy I would have found a much easier and better way. Like feed her a dozen donuts and chase her with a bear. She was obese and unfit.
