I remeber there was a show I watched when I was younger with my parents that was very good. It was animated. I think it was about this teenager who got caught up in this plot with aliens. It turned out he was an alien too or something. I think his dad's best friend was the one who told him or revealed it to him. I remeber they were on a spaceship when he revealed the secret. Does anyone know what I'm refering to? Sorry for the vague details but it's been a while.
