Out of anything he could have said, or had said, moving his fringe to reveal his scar - a scar that did match the tattoo that Ginny knew was inked into the skin of her inner right thigh - showed the first visible sign that she wasn't as convinced as she had been five minutes before. Mostly because she didn't have anything immediately in her mind to reply with, it was just far to eerie that both things would match, especially since she knew she wouldn't put something permanent on her body without it meaning something.
And, she knew that the tattoo vaguely had something to do with the husband that she was having trouble picturing or naming.
"I don't know you." she repeated, on the verge of panicking as certain pieces were falling together but the most important ones were unknown. The fact still remained that even if something was wrong with her, and it seemed that there was, Ginny wasn't so sure she was going to hand over her free will and well being to a man she didn't know, having a scar that matched her tattoo or otherwise.
