Bruce explains to the team that they're going to use a filtration system by pouring the water through six thicknesses of t-shirt, which will render it "90% pure." I'm not sure I would consider that pure enough for me on the say-so of someone I didn't know, but the tribe apparently decides to go along. Shane puts in his two sweaty cents by saying that Bruce is "incredibly neurotic." Yes, that makes Shane your mental diagnostician. Hey, they're building a new society; Probst says so at the beginning of every season. Somebody has to be in charge of rejuvenating the helping professions. Shane says that Bruce is constantly bringing up the fact that he's taught this and is certified in that: "I mean, of course it grates on my nerves." Of course, Shane is certified only in shit-fit-throwing, so you can see how he would feel threatened. I'm not even getting into the tiny tattoos yet. What Shane does with his grocery lists is not my problem.
Bruce filters some water for his tribe, as Aras explains that the entire group just sort of went along with it, even though they didn't know very much about it. Courtney expresses some concern to Bruce, calling herself "shocked and awed" that pouring water through a shirt will get bacteria out of it. Bruce tells her that it won't get all of it out, but that it will get most of it. And, really, brain-devouring amoebas in small numbers won't hurt you. President Beefcake explains in an interview what would probably be the most convincing thing to me about Bruce's routine, which is that Bruce was drinking the water himself, so he apparently at least believed himself to be right that it was safe to drink. ["Maybe Bruce has just never heard of Arnold Bennett." -- Wing Chun] President Beefcake also mentions that Bruce drank it and didn't die, which seems a little bit stupid, because it's not so much the instantaneous, Princess Bride death with the keeling over that's a problem here. It's the death three days later with your intestines hanging out of your navel and a badger crawling out of one of your eyes.
Bruce interviews that the tribe thought he was "a gift from heaven." You know, a little bit of that goes a long, long way. Very few people really want to hear a whole lot about your status as a gift from heaven. It's absolutely impossible for me to imagine a situation in which I would ever believe that letting that remark fly was a good idea. Back at camp, the members of Casaya all enjoy some 90% parasite-free water, which they do sorely need.
