My prediction are
Katie - Will be seen as patronising and too ruthless. Think the comment about not getting where she is by sitting home and playing mummy could go down badly - it does make her look slightly uncaring. I think she's a goner - especially after Sir Alan's Mirror column where he says he wants to punch her. This episode he can just get rid of the 3 he dislikes the most for ANY reason.
Kristina - Could fare well. Think she'll come across as intelligent and shrewd and will fight her corner.
Lohit - Think he could come unstuck as well, may look a bit like a damp squib so to speak. Him being quite quiet could go against him
Simon - I think he could do ok. He has a good personality and could win them over. He's made Sir Alan laugh twice this series (which could be some sort of record). He has good ideas and is willing to take risks, and I think ultimatley Sir Alan likes him. Even if he has a dodgy interview and so so feedback, he could go through on that basis alone.
Tre - I think he'll be cocky and slightly arrogant - looks like he comes unstuck. I don't honestly know how the interviewers would react to him. They disliked Paul for being cocky last year.
I think the Final 2 is going to be out of Kristina, Lohit and Simon. I can't decide which 2 though are more likely.
