indeed, i wonder if dehydration was the primary problem he was having as like you said he started to seem like he was getting better after they had him drink that gatorade or whatever it was.(im sure it was some sort of sports drink like that). The same thing happened to a camera man on the kodiak the first season it was on the show. i cant remember when they show the scene, im pretty sure it wasnt in the season or the after the catch so it must of been one of the other specials. the deadliest sea episode maybe?
