Nice catch on how hypocritical Kate is being by lying to Aaron about her parentage. If she's not careful someday Aaron will blow her up! It's great that Charlie was the one to point this out to her, I guess he's all knowing now since no one on the island knew what she did before the rescue. I'm glad that you had him driving a car, it helps to show that he's not a ghost, hallucination or smoke monster.
