One day Sonic went to Rouge's house, after hearing she stole some of the chaos emeralds, however she wasn't in, but her window was open... so Sonic went in anyway, hopping to snatch the emeralds back right under her nose. "see how she like someone else being sneaky, taking "her" gems for a change? " Sonic however when he tried, he managed to get into her room *fooling her machines to thinking he is Rouge* it tried to make Sonic look more like Rouge... soon the real Rouge came and caught Sonic.

instead of changing him back, she had a better idea, of using her mind washing machine; to make Sonic into her blue twin sister..... and partner in crime
