This was one of the few, rare times in Remus' life when he felt completely helpless. There was nothing he could do or say that would ease Dora's suffering. All the comforting words, the gentle touches would do absolutely nothing to cheer her. In this, he was totally useless.
He wasn't going to say that he could still smell it. That his sense of smell was stronger and he was still fighting the waves of nausea. He was forcing himself to stay calm, at least for her sake.
"You had no way of knowing," Remus said softly. "You were injured afterwards and I wasn't up to snuff either. You had no way of knowing so don't blame yourself, love." Remus lightly kissed Dora's temple, settling on one end of the couch and pulling her into his lap. "Are you sure it's her?" Remus asked softly, knowing full well it could have been any of the Death Eaters who did this act.
