Harry was walking down the street with his hands in his pocket. He had his symbols hidden when he can so no one could copy them. Plus with how they worked he didnt want to blow himself up by accident. While he walk a blood-curdling scream sounded out through the city. He just smirked because to him it sounded wonderful. 

As he walked he saw he was getting close to the meeting point of his fellow coalitionists. So he started making sure he wasnt being followed. No point getting caught now. Once he was sure it was all safe he walked up to the meeting point.
