He was scared somewhat, the flood potential did really bother him. Notice I said no duff, I told him that means tell me how you are really doing. He was definitely sore and cold too, shivering visible despite being in a neo-fleece, but we had to stop a lot for filming etc. I do wish they checked with me on the place names i.e. where they were, that's my only real gripe. As for helmet off, don't you take yours off in ducks, I sure do! (Though it was not needed with the water levels) I also take it off to film myself with my gopro see one of my Sleets gill vids for example, the camera's attached to the helmet, so that's nothing unusual when filming underground. Finally yes he did talk about dyeing too much, but I think he was genuinely nervous about the flood potential remember he had never done anything like this cave before, and I remember how nervous I was on my first trip in there. (Mainly because we did not have smart phones (that's how long ago it was) and used a newspaper as the weather forcast lol!)
