I just watched last night's Big Bro on my Sky Plus cause I missed it. And I just saw Marcus explain how every HM got in. I mean, all that stuff he said there, it would be almost impossible to do that when you're inside the Big Brother House yourself. I don't know how he figured that out. Sure, it's obvious the ones with Sophie or Carly - they're simply good looking. But the other theories he had on HMs like Rodrigo, Lisa, Angel, Sree etc was stunning.
Not many people in the world could of gone in and did what he just did there. All the stuff he said was absolute spot on for every single House Mate. I was amazed.
So basically, he's good at understanding Housemates. And I wouldn't be too surprised if Big Brother would want him to work for them next series.
He knows exactly what type of people goes good together inside the house, and which types clash with each other (such as Lisa clashing with Marcus). And that's why Marcus has stayed away from Lisa ever since he got in, he knew they would clash.
And not many people could of verbally beaten Lisa in an argument.
He's a genius
And sorry for my English, it's my third language and I'm still a bit drunk from last night
