Yeah, but I think we also have to keep in mind that they have to keep people on the show that they know is going to create constant drama (dude with all of the tattoos) or have us tuning in to see when they will finally kick their butt off (Angela) cause they don't show any real talent.
I was watching an episode on VH1 about the real secrets behind reality tv (I admit it

) and other reality show stars said that they had to fill out tons of quizes and personality tests about themselves. Then the shows have psychologists come in and tell them who is most likely to clash, create drama, etc. And that's who they keep around for ratings. So, Angela & Bradley may stay on until they choose the final 3.
