Why aren't you attacking me!? He let out a growl, Shadow wasn't the type of …hedgehog that would attack someone who wouldn't defend themselves, but he was angry. He approached to Mephiles without attacking but he concentrated his power under his hands, if he decided to attack, Shadow would happily reply with good doses of chaos energy based spears.
"Ah... you have done nothing you say. You put the whole world into jeopardy and you did nothing? You just have been the only being successful on killing the blue hedgehog! And you say you did nothing?!" Yelling was the only thing he could do for now to release his anger and frustration if Mephiles wouldn't attack him back. Why was he that angry at such actions? He knew... everybody knew he and the blue hedgehog weren't exactly what someone could call friends, but when he saw his lifeless body in the arms of that Princess, he was shocked, who would have thought that Sonic would ever be defeated?
Prisoners?... Whatever that meant, it attracted Shadow's attention. "Stop playing dumb with me Mephiles, I know firsthand you are able to twist and control time you cannot fool me with such lame plot of yours."
