That was pretty cool to see. We see that Little Mo had a hard time attatching to anyone because no one ever seemed to care for her. Even when she made a friend once, that friend was really only there to elevate her own status.
But the one person who truly became her friend was someone she could trust as an equal. Someone who criticized her and helped her. And from there, she learned how to gain confidence in herself. She took what she knew to do, and took it to a high level! 15 years later, Mo looks at 14-year old Little Mo, and sees someone who struggled, but persevered to become great.
