And in his final battle with Lord Voldemort,
Severus Snape's Patronus was also a doe, which symbolized his love for Lily. Snape uses his doe Patronus to show Dumbledore that he never fell out of love with Lily, his childhood best friend.
Lily's Patronus was always a Doe and James Patronus changed into a Stag when they fell in love. So JK said that when Lily and James fell in love, one of their patronuses changed to match their mate. She never mentioned whose Patronus changed.
Snape performed such a brave act in order to protect Harry Potter for the sole reason of his love and dedication to Lily. In the Deathly Hallows, Harry is specifically led to the sword of Gryffindor by a doe, which is revealed to be Severus Snape's Patronus.
A Patronus is said to change for a person to somebody else's Patronus form when that person dies, if you love them enough. For example, Lily's Patronus was a doe, yet Snape's Patronus was a doe too after Lily's death, meaning he loved her so much that he took that Patronus form in her memory (it changes without will).
To readers and fans of the films, Snape's backstory—that he was protecting Harry from Voldemort out of his never-ending love for Harry's mother, Lily—was not known until the seventh book and eighth movie.
Artemis's sacred animal was a deer. In Potter, Snape's Patronus, a soul-guarding magic spell, takes the form of a deer—more specifically, a doe—as a symbol of his love for Lily, because hers was a doe as well.
Narcissa Malfoy's Very Dangerous Lie
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.
He can't cast a Patronus
In a Q&A with Harry Potter fans on Twitter, J.K. Rowling was quizzed what Hagrid's Patronus would be. In reply, she wrote, 'Hagrid couldn't produce a Patronus. It's a very difficult spell. '
James's Animagus form was that of a stag, which earned him his nickname, Prongs. Strikingly, Harry's Patronus was a stag and his mother Lily's was a doe, a female deer, showing that the family's characters were in harmony and formed part of the same animal group.
Lily was an animagus too, when Voldemort attacked, she transformed in front of him so that she could attempt to escape. Voldemort hit her with a spell which locked her in her form as a twisted way of leaving her alive for Snape. Harry never noticed but there was always an animal watching him as he grew up.
Eileen Snape (née Prince) was the mother of Severus Snape. She was a pure-blooded witch who married a Muggle man named Tobias Snape. It is said that she was the original owner of the advanced Potions book that her son and Harry Potter would later come to own.
In these memories Harry saw Snape's frantic conferences with Dumbledore about the prophecy and how he begged for some way to keep Lily safe from Voldemort; and later, when her death made him wish for his own. Imagine squeezing out of the grasp of a murderer, and then working directly against him.
Yet despite the danger of his mission, and despite being hated by most of the wizarding world, Snape held on to the one thing that kept him going: the safety of Lily's son. He even sent his Patronus to guide Harry Potter to the sword of Gryffindor (a known Horcrux-killer) in a nearby lake.
Not knowing whether Draco was alive or dead, Narcissa chose to lie to the Dark Lord rather than risk losing her son. When Voldemort asked her to check if Harry was dead and she realised he was, in fact, still breathing, Narcissa seized her opportunity.
In a whisper, she asked if Draco was alive. When Harry replied quietly that he was, Narcissa betrayed the Dark Lord and asserted that Harry was dead. She knew the only way her family would be reunited was as part of Voldemort's conquering army, thus proving she loved her family more than she supported Voldemort.

In the film Harry Potter And The Half-Blood Prince, Narcissa Malfoy went to Severus Snape with her sister Bellatrix Lestrange. Narcissa asked Snape to make the Unbreakable Vow with her to protect her son Draco Malfoy as he attempts to perform the task asked by the Dark Lord, killing Albus Dumbledore.
In addition, the portrait of Dumbledore told Severus Snape that the sword must be taken under conditions of need and valour, which was why Snape put it into the frozen pond in the first place. As goblin's silver, it imbibed only substances which strengthened it, which could then be used against enemies.
An Unbreakable Vow is a magical spell of unknown incantation, in which one witch or wizard makes an oath to another. If either of the two break their terms, they die.
This nuance was lost on Lord Voldemort, who wrongly assumed Severus Snape held the Elder Wand because he was Dumbledore's killer, when in reality Draco had disarmed Dumbledore before Snape arrived on the scene, making Malfoy the wand's true new owner.
Voldemort intentionally made six Horcruxes, but when he used Avada Kedavra on Harry, he unintentionally created a seventh Horcrux. Instead of dying, Lily's love for Harry created a counter 'curse' known as Sacrificial Protection and saved Harry.
The Elder Wand would only give its allegiance to the one who defeated its previous owner. Voldemort killed Snape because of the mistaken assumption that the Elder Wand was loyal to him, but that was because he was not aware of the real chain of events.
