This, of course, hints at one of the most major twists in the entire series: the reveal in the final installment that Snape has been on Harry's side the entire time because of his love for Harry's mother, Lily, who was killed by Lord Voldemort.
Knowing that Snape has been on the Dumbledore's side for all seven of the Harry Potter books reveals him as an extremely brave man and a truly skilled spy. Snape has had to face and deceive the terrifying Lord Voldemort constantly.
Snape's fierce devotion to and love of his childhood friend Lily, Harry's mother, is the foundation of that loyalty. After Harry Potter and the Half-Blood Prince, Snape's loyalty was a matter of intense debate among the fans.
Most of the wizarding world rests securely on one side or the other. Snape, however, is outwardly loyal to both, but trusted entirely by neither.
Now, as firmly established, Snape was not the greatest fan of Harry, but that didn't mean that he ever stopped loving Lily. Dumbledore was surprised that Snape seemed to care for the boy. With a swish of his wand, Snape conjured up a Patronus – Lily's Patronus, a doe. 'Always,' he said.
As Rowling explained in a series of tweets, Snape loved Harry's mother, Lily, and his unrequited affection drove him to resent Harry's father, James — and by extension, Harry himself.
The acclaimed author explained that Harry paid tribute to Snape because of “forgiveness and gratitude.” Though Snape bullied Harry, he also saved him. “Harry hoped in his heart that he too would be forgiven.
She knew Snape was working for the Order - everyone in it did. Professor McGonagall knew that Snape was working with Dumbledore. Everyone in the Order did, which is why Snape was actually let into Order meetings - if they didn't know, they'd likely have tried to not let him it.
The final book, Deathly Hallows, explains this. Snape HAD BEEN a Death Eater. He later renounced his connections with that group, but no one besides Dumbledore knew for sure whether he had truly switched sides, or was just faking it. Dumbledore, alone, knew the truth.
He doesn't trust Snape as Dumbledore does, but he believes that he can detect any disloyalty. Moreover, Voldemort regards Snape as highly intelligent and therefore ' as a true Slytherin ' a person whose top priority is to take care of himself. To his twisted mind, selfless equals stupid.
There is no evidence to show that Voldemort ever knew Snape had betrayed him by revealing his plans to Dumbledore; on the contrary, there is a fair amount of circumstantial evidence to indicate that he didn't.
Dumbledore trusts Snape because he witnesses Snape's emotional devastation upon learning of Lily's death. Dumbledore himself knows that sort of devastation. It's akin to what he himself experiences when he contributes to his sister Ariana's death.
Dumbledore reveals how thoroughly he loves Harry. Harry is brave, and Dumbledore is proud as any father would be. More than that, Dumbledore succumbs to a parent's weakness; he cares more about Harry's happiness and wellbeing than the wizarding world he is trying to protect.
Draco Malfoy's mother Narcissa was cold, cunning and devoted to the Dark Lord. But she was also a mother, which meant she was willing to risk everything to make sure her son was safe. When Harry survived Voldemort's Killing Curse for the second time, Narcissa pretended he was dead so she could get to Draco.
Snape's Patronus is a Doe because of his outstanding love for Lily Evans, the mother of Harry Potter. Snape met Lily when they were children and immediately developed a crush on her.
Harry Potter: Stag
Harry's patronus is undoubtedly the most recognizable. The stag is first seen in Harry Potter and the Prisoner of Azkaban when it saves Harry and Sirius Black (Gary Oldman) from the dementors at the lake.
Later in the year, McGonagall duelled with Death Eater Alecto Carrow during the Battle in the Astronomy Tower and later learned of Snape's murder of Dumbledore. McGonagall was initially appointed as Headmistress, but was demoted after Voldemort took control of the school and placed Snape as Headmaster.
Draco's refusal to reveal Harry's identity to Bellatrix was not because he liked him. It was because he believed that Harry was the only chance they had at defeating Voldemort. At first, Draco admired and revered Voldemort until he threatened his family's safety.
This, of course, hints at one of the most major twists in the entire series: the reveal in the final installment that Snape has been on Harry's side the entire time because of his love for Harry's mother, Lily, who was killed by Lord Voldemort.
The Head of Slytherin is Horace Slughorn (who left the role to Severus Snape for fifteen years before taking it up again in 1996) and the House's patron ghost is the Bloody Baron.
She Screams When Harry 'Dies'
And this tips Minerva over the edge, with the Transfiguration teacher letting out a horrendous scream that pierces the air. Harry is actually alive, of course, but he's shocked that McGonagall could make such a noise.
Because she saw two alarming red flags in Severus' attitude. no real regrets for what he did. no real intentions to change.
Harry Potter named his son after the character Professor Severus Snape in tribute to him dying for “for Harry out of love for Lily [Potter],”JK Rowling revealed on Friday.
The reason that Lilly's death was a true sacrifice (as in she died though she needn't have) is the fact that Voldemort genuinely would have let her live if she had stepped aside and let him kill Harry. Snape convinced Voldemort to spare Lilly.
