Definitely.
Rebecca and Luke ARE Big Brother 9. They will be the housemates that are remembered, because, let's be honest, they are providing entertainment and the fact that they create so much opinions on this forum shows that they need to stay.
It's a shame though, Bex will go next, and Luke will follow a few weeks later, and then BB9, will be crap. Blunt but true, Kat,Rachel,Darnell,Rex may all be nice people, but they will not provide an hours worth of entertainment for the next 6 weeks. There's a reason why Bex and Luke are featured more, its because they are more entertaining, and the others, simply aren't.
IMO of course
