There was someone else there...she could hear the footsteps and see the light from some other source other then her wand. With a start, Ginny realized that she hadn't doused the light from her wand! Mouthing a curse, she couldn't believe she had been so careless. When she heard the voice, she just knew. Knew who it was even though it couldn't be possible.
"Hello back!"
Not thinking twice, she stood up and came out of hiding. Thinking this was some fun house illusion, she grinned at the other redhead in the room. It didn't look exactly like her, but she had this overwhelming sense that it was her. She was hot!
"I'm Ginny, who are you?" she asked, just to make sure.
