Inside her own mind she was arguing with him, saying that how could she protect herself when Harry had been killed by this witch and Ron had obviously been bested by her as well. She just managed to keep from saying it aloud, though, as he had enough on his plate with his brothers. He was just trying to make her feel better, and though she appreciated it, it didn't.
Gidget, however, did manage to make her feel better, if ony a little bit, as he was irresistible. For a moment, she wished she could live as a dog - nothing to worry about in live aside from when to eat, with whom to sleep, and where to poop.
"She'd better not show here," she finally said, cuddling Gidget to her chest. "You've a whole arsenal downstairs just ready to beat her back."
She tried for a smile as she said the words, but something even worse occurred to her. The witch wouldn't come for George, so the only reason she would come here would be to get Ally. If George was hurt, it would be her fault.
