Ginny switched her eyes somewhere else when Ron touched Hermione's hand. instead she looked at the table, taking in Hermione's words. She didn't want to think that this was caused from pent up grief over her brother, although the thought had occurred to her as well.
Maybe it was the flash of pink she saw before meeting the woman, going to George's all the time, Malfoy's comment on Fred, really it could have been a number of things, if it was this grief reason, Hermione seemed to be saying it was.
"Maybe she didn't hear," Ginny admitted a bit weakly, "It just gave me a shock, that's why I hadn't mentioned it."
This all made very good sense in her head, but she couldn't get that gut instinct to bugger the hell off already.
