Here's what happened:
* The Curse: During the Triwizard Tournament's second task, Harry and Cedric Diggory were both cursed with a spell designed to paralyze and drown them. The curse was cast by the Dark Mark, which was a symbol belonging to Lord Voldemort.
* Hermione's Intervention: Hermione, along with Ron, quickly realized the curse was targeting both Harry and Cedric. She bravely jumped into the lake to help them, risking her own life.
* The Effects: The spell meant for Harry and Cedric didn't actually target Hermione directly, but the water itself was cursed. Hermione was affected by the curse in the lake, becoming paralyzed and unable to breathe. She was saved by Harry, who used his ability to talk to snakes (Parseltongue) to control the water.
It's important to note: Hermione wasn't specifically targeted by the curse, but she was still significantly affected by it due to her presence in the cursed water. This act of courage and selflessness further highlights Hermione's character and her unwavering loyalty to her friends.
