Given that I have, so far, only seen her in Heroes I have to say that this girl has amazed me very much. Not only is she a very cute and charming girl, no she has talent. Like the character she plays in Heroes she is blessed with gift, and that is acting. She can show fear, happiness, panic... I don't know how she is 'backstage' but she seems very disciplined. I hope she has lots of fun in this and keeps on developing her skills.
I don't really like to compare things, or in this case people, but she reminds me of Dakota Fanning. Not looks or anything like that just their amazing acting talent at a very young age.
