I remember he did seem like a total twat in his VT, but he might have just acted that way to get in the house.
I've written a lot about him lately, so I won't go over it agian. I did like Siavash for the first half of the show. He was quite funny, level-headed, fair and everything. I enjoyed the team of Siavash, Marcus, Freddie and Noirin. I wanted them to get to the final together.
Then he kissed Noirin and that was over with (okay, Rabbitgate was before that, but it's so tedious let's just forget it ever happened.) I think at this point he just lost control and the cool exterior was revealed as a carfully constructed ruse.
He bullshitted A LOT. I never understood the reason why he "took himself out of the game" and refused to nominate. He gave so many different reasons it was impossible to tell which was the truth. And the most annoying thing was that if he, Marcus, Freddie (and Noirin and Bea and their other transiet allies) had tried to all nominate together they might have been able to get one of Team Cunt up and avoided the Marcus versus Freddie and Marcus versus Siavash evictions. But no, all his nomination refusals did was give an advantage to Lisa's gang and get good housemates evicted.
Also, the whole thing about wanting to leave two days before the final...what the fuck was that?
I do think he's a decent guy. If he'd managed to avoid the Noirin thing and keep his cool he could have been a contender. I guess he did well to get second place, but I can understand why he lost by such a massive percentage.
