Going to the Mansion again would not be wise for Remy. Here on the streets, Scott had to be careful not to hurt people. Last time Remy did his little attack, there weren't any teachers on hand to stop him. Scott guess he was proud to have beat a bunch of kids who didn't know what to do.
Looking over his shoulder, he watched him talking to a kid. That was kinda weird to see, but he didn't have anymore time to worry with it. Soon, he was exiting the rooftop door of a random building, where the X-was waiting to take him home.
