Finding... No-One

Its because he's orange isn't it?

If your only child's name is 'no one', what does that say about you?

Noooo this is sad :(

No! Nemo in Latin means lost!!!!!

Does that mean he is looking for a son he doesn't have? What if nemo's dad is just crazy, traumatized maybe by seeing his wife and kids brutally murdered and eaten in front of him, and so he wanders around the ocean looking for "no one".
