Flint wondered why the girl wasn't talking "Well I am on my way to the café .. why where you running so fast?" The girl intrigued Flint, he wasn't really one for social interaction, he couldn't get close to people because his cover might be blown. The downside was he lived a rather lonely life but that was the sacrifice he had to take when in his field of work. 
Flint began to walk again, hoping the girl would walk with him.
