HOW DID NORMAN GROW SO FAST LIKEㅡ

maybe there is a mass production of normans a he is just another test

Yup, that growth spurt seemed crazy but according to the timeline, he is now 14 years old and since he was under Peter Ratri's special facility, there's no doubt that he got proper diet (far better than Emma and her gang) and physical exercise for the advancement of his mental abilities. Even my midget younger brother grew up suddenly in 8th grade (not the face, the body) after he was enrolled in a military school......
