He snuggled against her, head against her back, purring softly, almost subvocally, but the gentle vibrations would be felt, hopefully helping to keep her asleep. As he rather doubted she had ever had a companion that wasn't trying to kill or enslave her, he doubted that they would have tried to encourage her to rest as he was, too intent on trying to run her into the ground before doing whatever to her. He knew she was exhausted, and needed as much rest as she could get.
