Emma Carter is Jack Carter's genious little sister. She has tecnicly passed all grades of school and has a High School diploma, despite being ten years old. She always carries around a laptop that she has modified to run on solar power and never needs to be recharged. (One hour in the sun is enough to keep it running for three weeks straight.) Everyone assumes she just plays video games on this all day, and they are mostly right, but in certian situations she is exteremly helpfull. She is very quiet and almost never cusses. If she does, it is an exteremly mild word. For instance, if she says "crap", it usually means that she has just found out that the world is coming to an end. She almost never talks, so people usually forget she is in the room with them, and she is very observant, which makes her an exteremly good spy.
