Draco knows the woods as well as he knows his way around the Malfoy drawing room, but even so, the faint light from the moon is mostly blocked by the trees, and he has to cast a dim lumos to avoid tripping over fallen logs. He reaches the oak grove, the darkest place in the forest, about five minutes before eleven and ends his lumos, but he keeps his wand in his hand. He’s tried not to guess who Tonks might be sending, because his mind will only focus on one possibility, and he tells himself it won’t be her. It won’t be Lupin or Tonks, because they’re too important as leaders. It also follows that Granger, Potter, and Ron Weasley are well-known to the public and would make excellent hostages, so they won’t be sent on this kind of mission. No, it’s much more likely to be somebody like Seamus Finnigan or Mandy Brocklehurst, somebody competent but not indispensable. That’s how he would make the decision if he were in charge, but of course, he’s a Slytherin. There’s no telling what a Hufflepuff might do.
