sun changed a LOT too. hard choice. but a good one! :)

i think sawyer changed alot. he used to be the character that only thought of himself but now he's taking more care for others, as an example with claire, he was very protective over her. he realizes that some people cannot defend for themselves and takes up the position of doing so for them. also in example with hurley, he wanted to go back for him. i really like this change in sawyer, it shows his soft side. : )

Sun Changed More.
Sawyer Changed A Lot Last Season.

has to be sawyer he clearly cares about other people on the island now

sawyer DiD change alot.. but remember how sun was in the first season? she didnt want anyone to know she talked english, she did everything anyone told her.. before she couldnt even leave her husband who she couldnt sand at the time....
she grew sooo much sronger!!

Sun changed a lot, but I think that I was more surprised that Sawyer changed, he really is a lot nicer now

I don't think Sawyer's changed - like i don't think this niceness has suddenly come from know where - but i do think he's let his guard down and decieded it's alrite for him to act that way now.

Where as i think Sun has actually changed - thinking that Jin is dead(i'm stilly full of hope that he's alive) has made her badass and alot less serene than she used to be.

He's pretty tall now.

Sun always had a slightly rebelious/baddass-ish side to her. Remember when Jin told her to button her top, but she ended up undoing it? Or when she killed Colleen on the Elizabeth?

All right, so she's deffiantly stepped it up a notch this season, but I think it was always somewhere in her.

But Sawyer? He had the whole "every man for himself" mentality, and now he's jumping out of helicopters to save people? Yes, he's deffiantly changed.

I think Sawyer changed a lot, due to the Island. But Sun is second. Wow! I almost fell out of my chair when she told her daddy that they are going to be buisness partners.

Sawyer change more that anyone... He´s now a Hero..

I'm too tired to read the comments, so forgive me if I'm saying what someone else has said already.

Sawyer has definitely changed the most. He used to be the most selfish character on the show, and somehow he is now the most selfless. He actually cares about people now. That's HUGE character growth.

A for Walt - he's most definitely the most changed physically, but we've barely seen him, so who knows if he's much different than when we last knew him?

He definately cares more about other people now and is more trustworthy.

Sawyer has changed.He use to be a person that only cared about himself and no one else.But then he started to become more caring and showing his feelings.

He keeps growing into a good guy

I didn't even have to think about it, Sawyer & I like good guys!
