Fenrir cleared all evidence that Rabastan had ever been inside his cottage as quickly as he could. While he cleaned up the mess left by the rather bloody murder, Hermione took a long, hot bath in the next room thinking over her limited options. She wasn't at full strength. If she was attacked again by Rodolphus, she didn't think that she would have much hope of being able to fight him off. The fact that she was able to stun him at all the night he drugged her was a miracle. If he hadn't made the mistake of turning his back on her and underestimating her as a threat while he threw his temper tantrum, she wouldn't have been successful.
