Her curiosity got the better of her, and she tried to open it, only to be rebuffed. Her determination rising, she tried again, and managed to get into the secret folder, only to find a strange code in a file.
But reading that code, and attempting to understand it, has set her mind ablaze. it was like the code was a living thing that has made it's way into her mind and body. With it "infecting" her, she found that her mind expanded, and she could control machines, and computers.
So, she has taken the identity of Interface, a new superheroine.
