Harry was baffled, he didn't know what had happened. He didn't know why he was here, from 2008 when Ginny was here from 2004. He didn't know how to explain it to her. All he could do was rush after her. "Ginny!" He yelled.
He didn't notice the luggage that followed after him, but he did notice the luggage that followed after Ginny. He thought that somehow she had got her magic to work enough to get the bags to follow.
