When Draco attempted to utilise the Cruciatus Curse, Harry retaliated with Sectumsempra, a spell he remembered having read about in the Half-Blood Prince's copy of Advanced Potion-Making, which caused deep slashes across Draco, heavily wounding him and causing him to fall to the waterlogged floor, his blood floating ...
Malfoy spots Harry and casts a Cruciatus curse; Harry, defending himself, using the Half-Blood Prince's Sectumsempra spell without knowing its effects. To his horror, it gashes Draco's face and chest, spilling his blood everywhere. Moaning Myrtle flies off, screaming.
Malfoy was born in a pure blood family and had no doubt heard of the baby who defeated Voldemort, which would have intrigued him. Therefore he tried to befriend Harry, but came off as rude, which got him rejected. He then proceeded to bully Harry and his friends to avenge the rejection.
Why didn't Harry get in trouble for hurting Draco?
When Harry critically injured Draco Malfoy with the Sectumsempra curse, it was actually enough to have him expelled, as Professor Minerva McGonagall stated Harry was lucky not to have been, due to Snape giving lenience to prevent others from finding out that he was the one who invented the curse.
Draco and his gang frequently antagonised Harry Potter and his friends, and Malfoy also used his position as prefect to bully some first years when he got the power in his fifth year. Their main target of hatred were Muggle-borns and Blood traitors alike.
Harry Potter had a few love interests during his time at Hogwarts. Though he eventually settled down with Ginny Weasley, he also had a thing for Cho Chang in his earlier school years. Then, of course, there's his secret love for Draco Malfoy…
It's safe to assume that Draco's hatred of Harry was fueled by jealousy. Although Draco attempted to disguise his jealousy with confidence, it still makes an appearance throughout the franchise.
There is likely a good reason that the Sectumsempra is not an unforgivable curse. It's mostly because Sectumsempra is Snape's personal curse that he created. It is not a widely known or used spell, and it is one that he kept secret — which means it can't be added to the list since no one really knows about it.
Vulnera Sanentur was the song-like incantation of a healing spell which was used to heal deep wounds, which could also be used as the counter-curse for the curse Sectumsempra.
Sectumsempra was a curse invented by Severus Snape that lacerated the target and caused severe haemorrhaging. Snape created it as a student of Hogwarts, with the intention of using it against his enemies, likely including the Marauders, with it becoming one of his specialities.
Personality. Draco is the prototypical spoiled, rich brat; he believes that his family's wealth and social position gives him the right to bully those poorer than himself, such as Ron Weasley.
While it may seem as though Draco simply has an outright hatred for Harry from the start, it goes deeper than that. He is, above all, jealous of Harry and a coward. Draco was brought up believing that he and his family are the best that the wizarding world has to offer.
History. Throughout the 1996–1997 school year, Draco Malfoy would go to the washroom to find company with Moaning Myrtle, confiding the stress of his mission and fear of failing it.
The Disarming Charm became Harry Potter's signature spell, and it notably caused the final defeat of Lord Voldemort during the Battle of Hogwarts by rebounding his Killing Curse, because the Elder Wand recognised Harry as its master through the spell connection, and thus strengthened the Disarming Charm to the point ...
No, nothing truly bad would happen to Harry externally. Internally is a different matter, Hermione didn't like Harry hurting Draco, she' hate him killing Draco, and there's no way Ron would be happy about it, although he'd try to support Harry. Dumbledore would be extremely upset about this whole deal as well.
Family. Snape's family background is mostly shown in flashbacks during the course of the last three novels. Snape was born to Eileen Prince, a witch, and Tobias Snape, a Muggle, making him a half-blood (hence the name, "Half-Blood Prince").
Sectumsempra derives from the Latin sectum, "having been cut" (comparable to the English word "section" or "segmented"), and possibly semper, "always." It can be translated as "always cutting" or "sever forever", the latter being a pun on Snape's first name, Severus, as well as indicating that severed body parts cannot ...
His tears were due to the fact that since the bird had died, he had failed once more to repair the Vanishing Cabinets. Draco needed to repair them in order to give the Death Eaters a safe way to infiltrate Hogwarts. Failure meant death, Voldemort had made that very clear.
Effect. Unforgivable Curses are the three most powerful and sinister spells known to the wizarding world, and are tools of the Dark Arts. They were first classified as "Unforgivable" in 1717. They are the Killing Curse, Avada Kedavra, the Cruciatus Curse, Crucio, and the Imperius Curse, Imperio.
In the final movie, Harry Potter and the Deathly Hallows pt. 2, Molly first hits Bella with a spell that freezes her, most likely Petrificus Totalus. Then, she launches another one that shatters her entire body into pieces, which could be expelliarmus, bombarda, stupefy, or any spell that can produce such an effect.
J.K. Rowling said that Draco had a crush on Hermione Granger, but he doesn't show that, beacuse Hermione was a Gryffindor, Harry's friend, and also a muggle-born. After the Battle for Hogwarts, Draco fell in love with Astoria Greengrass, and they had son Scorpius.
But in Harry's narration, where he was paying attention to the smallest steps Draco took, there was never a sexist behavior of him towards any girl. During the whole saga he was never close to any girl other than Pansy, and it was never confirmed whether they dated or not.
He fell in love with Astoria Malfoy, who didn't meet his family's pure-blood expectations, and was even willing to let the Malfoy bloodline end to protect her. This shift in Draco's beliefs shows his growth and development as a character throughout the series.
