Well, first of all, someone had to volunteer for a little odd job. That was Myra, she had to find an envelope from a photograph, and as a reward, she got to pick someone for an exemption to an exemption- that is, someone who could NOT get an exemption in this round. That someone? Dorothy of course. 
Then there were the diaries. Everyone has a diary, right? Some people wrote more than others in theirs. Well at the breakfast table, everyone had to pass theirs four to the right, to another person. Now everyone has someone else’s diary. Hey if that were me…I’d have died on the spot. Ahhh…:eek: So embarassing.
Then they had a competition for money. They had to cross a log over a lake/stream of water, and battle one of two people, Little John (a big ass dude) or Little Jane (also a badass, but smaller and female). The catch being that at least three people had to battle Little John (using these big rubber kayak paddle things)…and whoever got to the other side was able to battle for an exemption. Al was the matchmaker- he decided who would battle whom. Okay, so eventually, enough people got to the other side…two of whom were that big guy (Bill), and of course Al. Al fought Bill and won.
Oh yeah, did I mention Al not only won an exemption for himself, but for another member of the team? Bill said he didn’t want it b/c he “didn’t earn it” (Bill’s a real manly ex military type). Darwin that that was bull…but Al gave the second exemption to Katie (because the test did favor men, because Dorothy and Lisa were exempt, and because he had made Katie fight Little John in the previous round. Plus she’s the weakest member of the team, according to him, and he’d like as little competition as possible).
So then Lisa had to leave and that was it. Sorry if that wasn’t clear. I think I got everything, though. Nice try, Mahaloth! 
Maybe it IS Al. So unlikely it is likely? Darwin seems almost too obvious.
