Ron entered as they were wrapping up their exploration of the library to let her and Harry know that he had received a Patronus from Mr. Weasley and that his family was safe. There was no mention of Sirius or Remus in the message, and she could feel Harry tense beside her, but Ron was oblivious to the tension, only focused on the relief he was felt for his own family. She was thankful to hear that the Weasley family was still intact, but she was irritated at his carelessness of Harry's feelings.
