There seemed very little reason to sit around worrying about what she couldn't control. Draco was intelligent enough to survive over twenty years as a Death Eater when he was frequently the target of hatred and scorn from his fellows. And if he was to be believed, he'd been able to spend at least the last ten years in some sort of alliance with the Resistance. He was, in essence, a spy for the organization they had supposedly dedicated their lives to eradicating. If he was able to spend that many years moving between the two groups without getting caught, surely he would be able to find a little bit of polyjuice potion. If he wasn't successful, however, she needed to be ready with a backup plan. It would do no one any good to put all of her hopes on the one plan.
