Merlin knows Fleur needs all the help she can get in their makeshift infirmary, so Draco spends as much time as he can brewing potions and learning more about their uses. Sourcing potion ingredients is difficult, and he finds himself at a point where he has to ask Longbottom for help. Longbottom knows where every patch of lavender or dittany is, wild or cultivated, and while he’s not bad at brewing himself, he’d rather gather or cultivate the plants and leave the potion making to Draco and Fleur. Draco borrows Bill Weasley’s broom and goes out to collect potion ingredients at dusk, when he’s unlikely to be seen.
