Haven't been here for years - that said all she needed to say to Ginny. "Muggleborn?" Ginny asked quietly. Without waiting for a response, she continued, "It's gotten better. I mean, it's not perfect, but hey, we won the war. I'm sorry you felt you had to stay away - I know Kingsley was trying to make sure everyone knew they could come back. It's just not right to stay away from your birthright, you know? So what brought you back?"
She could afford to be even later (19 minutes and counting) to talk to this woman; she was certain her editor would understand. The unfairness of it was going to hit Ginny like a sack of bricks later. It wasn't fair that whomever this was had stayed away for so long. It wasn't fair they hadn't found her earlier and brought her back. Nothing about the war had been fair, but this simple injustice tore deeply at Ginny.
The idea that this woman could have been caught by the Snatchers didn't even occur to Ginny until it was too late (that was a problem with Ginny, from time to time), so she really hoped it was just a case of fleeing and never coming back, otherwise she was going to have to eat some serious crow.
And if there was one thing Ginny hated more than anything, it was eating crow.
