Things You Didn't Know About The Battle Of Hogwarts If You've Only Seen The 'Harry Potter' Movies

The climax of the Battle of Hogwarts sees only two duels remaining: Bellatrix vs. Molly Weasley, and Voldemort vs. Minerva McGonagall, Horace Slughorn, and Kingsley Shacklebolt.

Voldemort battles his former mentor, the current headmistress of Hogwarts, and a powerful Auror all by himself - his opponents try and fail to put him down despite attacking him at the same time. 

Their duel is so remarkable that people present at the battle line up against the walls and simply watch the wizards fight. Voldemort ultimately wins when Bellatrix is slain and he furiously blasts all three of his opponents back to knock them out.

The Giants stand by their decision to join Voldemort's cause and join the Battle of Hogwarts fighting for his side. Of the heroes, Grawp is the only one of his kind who seeks to protect Hogwarts.

Grawp joins the fray alongside Hagrid and engages the other giants. Harry notes how small Grawp is compared with the others, realizing Grawp is an undersized giant after all. Nevertheless, Grawp ends up as the only giant left standing by the end of the battle, and the survivors throw food into his mouth as part of the victory celebrations.

Harry and Voldemort are both transported to limbo after the latter attempts to slay him with the killing curse. While talking to Albus Dumbledore, Harry notices Voldemort in a grotesque form, filled with pain and fear. 

After returning to the living, Harry realizes this will be Voldemort's ultimate fate after the destruction of the final Horcrux. Despite everything Voldemort has done, Harry takes pity on his rival during their final clash and asks him to show remorse.

Since true remorse is the only way to heal a person's soul after it's been shattered by the creation of Horcruxes, Voldemort is given one last chance by Harry to make things right.

The Dark Lord is both angered and frightened by Harry's genuine plea but chooses to take it as an insult. The moment goes to show how evil Voldemort is supposed to be and how strong the power of love within Harry is to feel empathy for his greatest enemy.

Unlike in the film, Ron and Hermione don't make their feelings clear after they've destroyed the Cup Horcrux. In the book, Ron and Hermione bring along a number of Basilisk fangs with them from the Chamber of Secrets to Harry. 

After Harry proposes they search for the Diadem Horcrux in the Room of Requirement, Ron remembers that they haven't warned the house-elves of the battle. Hermione is touched to realize he wants to save the lives of the creatures she's tried so hard to protect and decides to profess her feelings by kissing him.

Ron and Hermione are so enthusiastic in their embrace that they completely forget about Harry - he has to remind them that they're in the middle of a war for Ron and Hermione to remember his presence.

Molly's defeat of Bellatrix is because the latter takes Molly very lightly. Molly initiates the fight when Bellatrix attempts to slay Ginny, but Bellatrix isn't shaken by her opponent's offense.

Bellatrix then makes the mistake of taunting Molly's family, asking what would happen to them "when Mummy’s gone the same way as Freddie?" 

Bellatrix's words infuriate Molly to the point where she's overtaken by bloodlust and she capitalizes on Bellatrix wasting her time cackling - Molly hits Bellatrix with a curse that stops her heart, instantly slaying her rival.

Snape is essentially sacked from his position as Headmaster by McGonagall after their duel. The film version is brief and Snape doesn't retaliate against McGonagall's offense, but they have a full-on duel in the novel.

After Snape uses Legilimency on McGonagall to figure out Harry is nearby, she initiates the battle between them. McGonagall uses a slashing curse that Snape blocks with a powerful Shield Charm. He knocks McGonagall off balance, but she recovers to create a massive ring of fire to use as a lasso on Snape. He then turns the fire into a huge serpent that McGonagall blasts into smoke. 

Their exchange comes to an end when McGonagall transfigures smoke into daggers that chase after Snape, who's forced to hide behind a suit of armor. McGonagall has the upper hand before the rest of the faculty arrive and Snape flees.
