If my nose doesn’t deceive me, I can smell a handful of questionable potions being brewed, and in highly dubious conditions to boot. Polyjuice potions seem to be bubbling (at the incorrect time for it to do so I might add), I most definitely smell Amortentia (since Draco’s unique scent of fresh parchment, spearmint and cedar wafts out at me). Let’s not even mention the highly illegal amount of Felix Felicis being brewed.. but the real fright is the Emerald and Death potions. Those are never to be brewed under any circumstances. It’s quite literally against the law to make those two particular ones, as they are more than just nasty, they’re deadly.
