Neville Melts His Cauldron in Potions

Neville Longbottom melts his sixth cauldron in Potions class, and Professor Snape gives him detention. Neville is forced to disembowel a barrel of horned toads, which leaves him in a state of nervous collapse. Ron Weasley and Harry Potter discuss how Snape's foul mood is likely due to Alastor Moody being hired as the Defense Against the Dark Arts teacher, a position Snape has long coveted.
