My main man is Jon Snow, he's turned out fantastic considering he has plenty of reasons to be bitter/spiteful.
snow, daenerys, then bran who think has the most exciting adventure on the book.
It used to be Jon Snow, before he ditched his wildling girlfriend and betrayed them.<br />
Now it's Tyrion Lannister.<br />
Oddly enough, I also like Jaime Lannister. I hated him before, but he's improved a lot as a person.
