It's always hard to lose someone you look up to.
Mom always told me that he would abandon me. She always said that he would never be true; he would be with me as long as it was convenient, and then abandon me when something better came along. I never thought it would come true... and in a strange sort of way, in a way that's not his fault... he has.
It's my fault.
It's my fault he abandoned me... because my reason abandoned me. But I won't abandon his last request... I can't let Eggman get the real emerald... I'll protect it with my life if I have to.
