Re #638 and #641, and those pics upthread of the person with white near torso and neck.
I agree with Greenperson, that it is of a male.
Medium build, bluejeans, dark short sleeve shirt.
Fits description of grey haired swimmer guy Phil.
Stepping through vid, during the cabin scenes with Ferd standing, show him with dark green short sleeve shirt & bluejeans.
Phil, not Ferd, has the dark green shortsleeve shirt.
Can you send a screenshot of the green shirt and blue jeans inside the cabin?
