I don't actually think Derek has much of a game plan, no more than Craig, Anthony and Makosi who spent all of last night positioning themselves for the last week.

Whatever game plan Derek has may be more apparent than the others because he appears not to have much knowledge about what the public like to see from housemates - the other HMs have probably watched previous series much more.

I think the simple explanation for why he bitches about the other housemates is he doesn't find much in common with most of them. I think the age difference is a huge factor on Big Brother, and combined with Derek's snobbishness it sets apart him from the other housemates, with a few exceptions.
