Ginny didn't let go of Neville throughout the whole ceremony. They had sat near Parvati, who was leaning on George, but Ginny hadnt' paid much attention to the whole proceedings. All she could think was What if it had been Neville? It was a thought that kept her up at night, even when she tried not to think like that.
She only knew, if she ever lost Neville she wouldn't be able to go on. Wouldn't want to. Without her really even realizing it, he had become her whole world over the past year, and she would do whatever she could to keep him safe.
She realized that Neville was talking, and pulled her thoughts from losing Neville. "Yeah, let's go say hi to Cass and Percy. It's good to see them both out and about." She tucked her arm through Neville's, and led them in that direction.
