I'm going out on a limb here but.....
I like Marcus.
Why?
Because I don't actually believe that he believes half of the things that he says. He's a complete bullsh*tter. He says 'dodgy' things because he wants to provoke a reaction. I'm his age and although I'm not like him, I know people just like him. Saying things that may offend, but with no real malice behind them. Like a joke that if you get it, you get it, but if you don't then tough! In this respect, I think Noirin 'gets' Marcus and so do a few others.
Tomorrow night, watch Marcus with a sense of irony � like he's been given the task of winding some of the housemates up...
Prediction � Marcus will not win, but he'll be there right to the end.
