So after 'Steven Birthday' aired, we learned that Steven was 14. That means we say him turn 13 in 'So Many Birthdays', and that he began the series at 12 years old. It's really cool how characters can grow in the show, not generally physically, but definitely in maturity and knowledge. Steven never went to school, but seems intelligent enough. He seems to be very new to going on missions with the gems, so what exactly did he do with his time before that? Connie's life is full of school and lessons and extra curricular activities, which often leaves Steven waiting for her. And the gems often go on missions without him, leaving Steven to worry. He's really stuck between two different worlds, neither of which he seems to fit into. Check out The Mary Sue's review at the link below!
