They couldn’t beat Hermione’s impressive mastery of astrology and astronomy, but Theo just had the edge on her for practical knowledge of herbology. Sometimes Hermione’s answers included extinct magical plants like silphium and moly that hadn’t been used for many centuries, which got a laugh from Draco and a rueful concession from Hermione that some of her information may be a little out of date. Draco clearly was the best of the three of them at potions, having had ample opportunities in the past to actually brew things, which kept him content despite being beaten at other questions. When the cart came around they were all happy to take a break to have some lunch (but not as happy as the increasingly stressed duo of Vincent and Gregory were).
