I watched and watched ... freeze/go/freeze/go/freeze .. etc.
What I saw was one person that may have been a heavy woman look at something in the water that appeared to be moving and what appeared to be moving appeared to swim up the that person and then veer off
All the while, the head of the woman? tracking the appearance.
If that was Fuddy ... she got out, was floating peacefully? and... then what ?
It sure APPEARS to be a scuba swimmer in a black wetsuit? swimming up and swimming away.
SOMETHING moved towards the woman floating then veered off to my left (as I see the film)
Does it seem to you that what came up and veered to the left was one of the 9 people who were supposed to be the only ones there? Why or why not?
