I hated Eugene the first time I watched BB6 but on the rewatch he was a welcome bit of niceness, really. He had some sweet friendships with Derek, Kinga and Makosi, and he had the odd funny moment. Genuine oddball though (not that that's a bad thing).

I think the best arguments were Mary vs. Saskia, Science vs. Maxwell and Kemal vs. Roberto (well, any of them).
