"I never wanted it to be a group of teenagers who were pally from the very start. I hate that convention in teen drama where they meet and instantly become high-fiving friends for no apparent reason. I felt I had to really work for that as a writer and earn the right for them to have a relationship. It's a gradual process; it has to feel organic. When one of the characters gets in trouble in episode two, they don't immediately say, "Yes, let us help you, now we are the Fantastic Four we must work together to fight crime!" It can't work like that."

"More important than any message for me was the question of how you handle being a superhero when society is already looking down on you. That's the experience of a young offender. It's also about having the responsibility of greater powers; my characters don't always use it for the greater good. That's where the fun starts."

"I guess that's why I never felt it was an impossible challenge to get into the mind of a teenager. I'm 36 now but I'm pretty certain falling in love at 16 is the same as it was 20 years ago"
