I think it's hard to change accent and be so cruel and so sweet and romantic at the same time. And his faces in Goodbye Gossip girl when Blair told ILY again - you have to be a good actor to do that.

And also Leighton as Blair because I can't cry when I want in sad moments, she can start to cry whenever she has to, at least in the show.

I think it is blair waldorf becasue you can see her in many faces ..she has a lot to suffer than any other characters in the show ..
she is the beauty,vain ,popular,Hated,Hypocritical,Loved,unloved,­Det­hro­ned­, Queen,Trusting,Friend,Broken,Betrayed,Sedu­cti­ve etc,, and about the Ed's accent I have seen a lot of britch who has american accent it is not a big deal and alos don't forget blair's dreams she got to talk in an accent I don't know which accent was but I think may be britch ..while ed's character is not that complix he was a womanizer and now he is in love ..his magic character has almost gone in this season .. the second one could be either serena or jenny since they both have changed .. or maybe could be dan LOOL .. that is just my opinion <<<

The complexity of B`s character`s just WOW.

DEFF!
And Chuck Bass.

without a doubt. i mean, he is an orphan, he was in love with his best's friend girlfriend, he never felt loved for anybody before blair, chuck's life was so tough in the first two seasons.

ed because of his accent change

agree with xxshannen1xx and besides chuck's character has a lot of changes in this 2 seasons

The accent change has nothing to do with the complexity of a character.
By complicated character, it means which character had been through very tough situations the most, which one had changed the most, etc...

Blair used to be a lot more complex than she is now. I feel like the writers are just using her for comedy these days. Chuck, however... Has motives behind everything he does because of his issues with his dad. No matter how far he gets in life, he will always be trying to get past it. On the surface, someone could see him as a womanizing jerk... But there's so much more to him than what you see there. Especially since now he's in love with Blair, but I'm too lazy to type more about all that. :P

I agree with iLoveChair, I was just about to say; what does Ed changing his accent have to do with anything?
I think it's between Blair, Chuck, & Serena, they've had the biggest storylines about their troubles, and have had more explanation as to why they are who they are.

I think Chuck is like an onion (yes I finally get to use a Sherk analoge) he has layers. There is so much about him that we are still - now with the help of Blair - slowly peeling away. I think Blair is complex aswell, but she seems to be more willing to show different sides of her self.

Well I think it's between Chuck & Blair. There's so much to them than what we see at first. They might not make good impressions on the people they meet, but they are more complicated than what we get at first glance. There's many reasons behind their actions, they are multifaceted, they are not all nice or al bad, it's not black or white, there's a lot to them to explore.
I picked Chuck because of how much the character progressed and grew throguhout the two seasons. He's a very complex character.

I would've prefered to pick BOTH Chuck and Blair because I believe both to be extremely complicated, complex and intriguing. Since Chuck had more picks I helped out Blair along the way but one of the choices should've honestly been Both.

No question.

chuck and blair both are complexed. You find out something new about them each week, i couldnt pick, but i knew everyone would pick chuck so i went with blair.

Blair and Ed!

I think after Blair&Chuck who are both really complex, with many many layers... After them two probably Jenny, or sometimes and in some cases Serena...

Blair or Serena they both had more screentime than others so I would pick blair she went through many ..

i like him so much but he is the most comlicated charcter in the show

I think Chuck's pretty easy to work out. It's pretty obvious why he is the way he is and you can always tell how he's going to react to any given situation. Blair however, is different, sometimes she's just full of suprises. And sometimes I can't work out why she acts the way she does.
