KIDS TRIVIA

Detailed explanation-1: -On his way back, Harry learns that the cloaked figure was Voldemort and that he was drinking unicorn blood to sustain himself until he could obtain the Sorcerer’s Stone.

Detailed explanation-2: -Drinking the blood of a unicorn would keep someone alive – even if they were an inch from death. However, it is considered an act of evil to kill something so pure. As a result, from the moment the blood touched someone’s lips, they would be condemned to live a cursed life.

Detailed explanation-3: -Even after Voldemort returned to full strength in his own body, he was still forced to drink unicorn blood in order to remain alive and strong. To do so, he was able to create a specific potion using unicorn blood and venom from the snake Nagini.

Detailed explanation-4: -In the words of centaur Firenze: ‘The blood of a unicorn will keep you alive, even if you are an inch from death, but at a terrible price. You have slain something pure and defenceless to save yourself, and you will have but a half life, a cursed life, from the moment the blood touches your lips.

Detailed explanation-5: -Alternatively, unicorn blood was one of the ingredients in the potion that allowed Voldemort to take his weakened baby-like form before his body was fully restored. So it’s possible that by drinking the blood, Quirrell was somehow allowing Voldemort to create a physical face.
