Gray found Carmen, and he didn't want to be in VILE anymore. He went on a caper and never came back. Carmen, not wanting Gray's life to get more dangerous, she ran to VILE island (they recovered it) and pretended to surrender to VILE. When Gray found out, he was so hurt, he cried his eyes out (not really). He had left to join Carmen, and now she had left him again. Feeling betrayed, he went home to his flat in Sydney.
People, this is the world's worst story. I hate what I wrote, and sorry its bad. Please don't read it if you haven't yet.
