I knew this was going to happen one day. This is worse than when Marlene found her brother's stash.
I told Slughorn, I said to him, 'Darling, sweet Professor, dungeons are not a suitable location for potion work. You need proper ventilation.' Now I've gone and breathed in enough fumes to form a full and very vivid hallucination, and I'll probably wake up to the Bloody Baron staring at me, passed out and drooling on the floor like I found Slughorn's firewhiskey.
