In this book, Draco is, for the first time since being introduced in the series, portrayed as having considerable initiative, ingenuity, and perseverance. However, unlike Harry, who always relies on his friends' support and help, Draco mostly works alone in the Room of Requirement, refusing to confide in or involve his own circle of friends, whom he treats more as underlings. This, and the realisation of what he is ultimately expected to do, nearly drives him to a nervous breakdown. When Harry walks in on Malfoy crying in Moaning Myrtle's bathroom, Draco attempts to cast the Cruciatus Curse. Harry is faster to the draw with an obscure "Sectumsempra" spell that he learned from the mysterious Half-Blood Prince's book. The spell cuts deep gashes into Malfoy's face and chest, resulting in severe blood loss. Snape, alerted by Myrtle's screams, swiftly arrives and heals Draco's cuts, then takes him to the hospital wing.
