Dobby's Freedom

Lucius Malfoy storms into Dumbledore's office, furious that Dumbledore has returned. Dumbledore reveals that the other governors have reinstated him and that Malfoy's plot has been exposed. Harry, realizing that Dobby is Malfoy's house-elf, tricks Malfoy into giving Dobby a sock, which, according to house-elf law, sets him free. Dobby is overjoyed and uses his newfound freedom to protect Harry, throwing Malfoy down the stairs. Malfoy leaves in disgrace, and Dobby thanks Harry profusely. The act of freeing Dobby is a moment of triumph for Harry, who has not only saved Ginny and the school but also liberated a being from servitude. Dobby's freedom symbolizes the defeat of the Malfoys' dark influence.
