Harry felt very intimidated by the young girl's brother, who was now standing between them, even though they seemed to be the same age and approximately the same height and weight, but for Harry who wasn't used to other people then the Dursleys, this boy seemed intimidating.
"What do you want?" Ron asked the boy, now in front of him, in a very harsh tone, continuously shielding Ginny from the stranger. "Sssss… sorry" Harry stuttered with a small fragile voice, barely any higher than a whisper and tried to back away, but found that someone tall was standing behind him. Harry felt trapped and regretted coming over.
