I say syd for me cuz im a girl, im stubborn, i'd also be fit to be derevko but im not too evil, hehe. And come to think of it there are only 2 main characters who are girls, there are supporting actresses, but so many guys and 2 main girls, this blows. Lol, so i guess im syd, another reason is cuz im not old, lol
I'd say Irina...I'm cunning, stuborn, and would be more than happy to get rid of anyone in my way. I would also be more than happy to have a false marriage, and chill in a CIA cell. ANd I don't think I'd make a very good syd, I'm not sympathetic enough.
