I am known as the phantom of the sewers. The turtles could only see me when they were young. I played with them every day. I was their friend. I watched them grow. When they moved deeper into the sewers is when they started to spread apart.
It started when Leonardo started having feelings Michelangelo. He was the oldest, and went through puberty first. When this happened Leonardo stopped seeing me. I could still see and hear him. He started hiding away from himself, and in turn, from his brothers.
Next was Raphael. He started having an attraction to Leonardo. He would whisper his name in some dreams, and when he learned to masturbate, would just manage to not shout Leonardo's name. He became grouchy, part of that being a lack of satisfaction. He had already fallen in love with Leonardo by the time he realized how much he wanted what he could never have.
When Donatello went through puberty nothing really changed for him. He continued to work in his lab, and fix things around the new lair. It took me awhile to notice that he was becoming dangers, less emotion, caring, love, and feeling. He was becoming all brain, now body.
And then we have Michelangelo. Nothing changed for him. Not for a long time. He could still see me, and talk with me long after he went through puberty. That stayed the same for a long time. Longer then I would have ever imagined, but, it did one day end. It ended the day he fell for Casey Jones.
Now, April O'Neil came into the lair. Oh, how I loved her being around. She brought all of the emotions, caring, love, and feelings back to Donatello. He was alive, but my love for her ended two months later when she developed feelings for Raphael.
When Casey Jones came into the picture I was peaceful. Raphael had a friend, and Michelangelo had a small crush. The only down side was that he really liked Donatello. That large crush was covered up by the fighting with Donatello for April O'Neil.
Splinter I have paid some attention to. He is skilled, and watches over them, but is about as useful to them as I am. I see everything, but can do nothing about it. He can do everything about it, but chooses not to say a thing. The only time he talks, or teaches, or has anything to do with them is when they need him to.
And then you have me. I am real, but not real. I am like a ghost. I don't know what I am. Michelangelo calls me the Phantom of the sewers, and so that is what I go by. If I see children, or adult that can see me, I help them back to their homes. I know these sewers better than anyone else.
