Within the week they had a decent plan in place. The first part of their plan hinged on Hermione’s considerable skill with potions. Out of necessity in the past year Harry had become quite adept in many fields of magic that before had merely been school work before. Despite this, he never did get the hang of potions, so that left the work to Hermione. The second part of their plan was an honest to Merlin random stroke of luck, as both he and Hermione were quite fluent in French. Hermione due to many summers spent in France as a child and Harry due to, in part a kind primary school teacher who noticed his fascination with the language, and in another part due to his continued practice with it during his fourth year with the Beauxbatons students. As they were both quite rusty, they deigned to only speak in the language unless absolutely necessary to do otherwise, they needed to be in the habit of using it first before English, lest they be found suspicious.
