X-Ray said:From what we've seen on previous episodes. He's obviously going by what he reads/sees on the news/newspaper. He sees this ***** one day and thinks she's a "super". I think he kills her before realizing that Claire is the super one and goes after her. By this time Pete should have arrived to save the day.
there wasn't anything in the newspaper or news about that girl in the diner who could remember stuff easily. So I dont think that theory is true.
