"Yeah I could tell, Lupin took me by her as well, are there really no redheads here?" This would be interesting at the least, Sirius Black and her chatting and hanging out, this was a scene she'd never thought of before. Ginny took notice of his reaction when she introduced herself, perhaps Lupin had mentioned her, perhaps he'd got that she knew of his little secret.
Ginny wasn't overly pleased to have him take his arm from around her, but she understood the action, it wasn't the most normal way to meet someone entirely new. She tried to ignore how nice and flattering sounded her name on his lips, screening it out as the same eagerness to see what this old world was about.
"I guess Hogwarts is always the same..." She commented on with a sort of dreamy perhaps nostalgic tone.
