Tyrion is my favorite so far. Daenerys is also a favorite, the way she stood up to her brother. Arya is also up there. The way she don't seem contempt with being a pretty face that will marry into wealth and power, but rather be strong on her own merits and perhaps take the power by her own hand one day. I guess i like people who stands up for themselves, and do what they feel is right even though the social protocol says otherwise.
