In the heat of the moment, Snape lost control and called Lily the forbidden word. He was embarrassed. He called her a mud-blood by accident because he was frustrated that lily did not like his closest friends.
In the book, we learn that James Potter and his friends were bullying Snape, and Lily came to his defense. Instead of accepting her act of kindness, he rejected her and called her a "mudblood" — an insult to witches and wizards with Muggle parents — despite his own impure bloodline.
That's right, Snape called Lily a mudblood, the worst possible thing you can call a witch with muggle parents. Granted, Snape said it in the heat of the moment while fighting against James and his entire group of Marauders, but there are no takebacks from something like that.
Snape's love for Lily fed his hatred for James, and meant he would stop at nothing ' even arranging the murder of her child ' to possess Lily. Lily's life would be spared in return for Snape giving information of the prophesy to Lord Voldemort.
If Snape never called Lily a Mudblood, it's likely that their friendship would have remained intact. This means that Severus would not have joined Voldemort and become a Death Eater, and Lily may not have married James Potter.
And although she was one of the few people at Hogwarts who was entirely unimpressed by him, her fellow Gryffindor James Potter was also deeply infatuated with her as well. Obviously Lily ultimately chose James Potter over Severus Snape, and Lily and James got married and had their only child, Harry Potter.
A Professor at Hogwarts School of Witchcraft and Wizardry, Snape is hostile to Harry due to his resemblance to his father James Potter, who bullied Snape during their time together at Hogwarts. As the series progresses, Snape's character becomes more layered and enigmatic.
While we know Voldemort killed Lily, he did give her a choice. If she stepped aside and allowed him to murder Harry, he would spare her. Lily refused and sacrificed herself to save her son. That action (and Lily's love) was what gave Harry protection from Voldemort's Killing Curse.
In "Deathly Hallows," Snape also uses his Patronus to help Harry on his quest to find Voldemort's horcruxes; a Patronus charm can be used to send messages, and Harry seems to subconsciously recognize the doe as an extension of his mother, allowing him to trust it.
Because she saw two alarming red flags in Severus' attitude. no real regrets for what he did. no real intentions to change.
In order to conjure the avada kedavra curse, you have to want to kill your victim. We all know that Voldemort could easily kill a child without an ounce of remorse... but not Snape. Snape didn't want to kill Dumbledore, and this was why the spell was blue instead of the usual green.
As Petunia was the Muggle sister, it wasn't long before Snape turned on her, using his power to make a branch fall and hit her. As well as the physical damage, he added further insult to injury by emotionally hurting her too.
Both Lily and James Potter were killed by Voldemort aged 21 at Godric's Hollow on 31 October 1981, when Harry was just 1 year old, And the rest of the story, you no doubt know.
He has a deep rooted phobia of shampoo. People do have different priorities, even if he ever washed it he probably didn't use enough shampoo or other products to get all the grease away.
They were close friends, she saw in him someone special that she could care about. But she couldn't be with him. So, it seems like it was very unlikely that Lily ever found out Snape loved her.
Because Lily (according to them) had the nerve to not fall in love with her former childhood friend, Severus Snape and marry that no-good-evil-spoiled-rich-brat James Potter.
1 Albatross
As the rarest Patronus in the Wizarding World possible, the Albatross represents an enormous bird that flies freely across any sea. This rare Patronus represents those who are simultaneously fearless, optimistic, happy-go-lucky, and ambitious.
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.
So when Ron said three, it wasn't a mistake. He meant there were three more horcruxes to destroy before being able to destroy the fourth and final piece which was in fact Voldemort himself.
We can therefore presumably safely conclude that Lily was not noticeably pregnant at the time she died.
Why is he incapable of love? Eventually, J.K. Rowling revealed to us that the reason Voldemort is unable to feel love is because he was conceived under the influence of a love potion.
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 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.
Snape hated Neville because he was a daily reminder Lily Potter could have lived. Snape's guilt over his part in her being targeted by Voldemort in the first place was bad enough, but to see a living, breathing reminder that things could have played out differently even after that act made Snape particularly vicious.
He was more jealous of Harry than he let on
Specifically, Draco was jealous of Harry. It was easy to miss because Draco didn't often show his emotions, modelling himself on his cold, confident, calculating father, but J.K. Rowling has confirmed that a lot of his enmity towards Harry stemmed from envy.
