When Snape heard the prophecy and pleaded with Voldemort to spare Lily's life, he may have inadvertently caused his downfall. 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.
After Snape overheard the part of the prophecy he did, he told Voldemort about it. Voldemort determined it referred to Lily's child, and Snape asked him to spare her. Then he went the extra step and told Dumbledore in an effort to save her.
We know, by way of The Prince's Tale chapter in Deathly Hallows, that Snape turned on Voldemort when he realized that his master meant to kill Lily Potter. He goes looking for Dumbledore, and they have this exchange: “Hide them all, then,” he croaked. “Keep her — them — safe.
Voldemort grants Snape's request to spare Lily because Lily's life is not important to him. Snape has done him a solid by reporting on the overheard prophesy, so this is an opportunity for Voldemort to appear magnanimous.
Their childhood and how their friendship developed, and crashed and still meant the world to Snape. Snape's obsession with Lily is therefore not just about her physical beauty or charm, but also about the fact that she represented a kind of emotional sanctuary for him.
We can therefore presumably safely conclude that Lily was not noticeably pregnant at the time she died.
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.
Her leaving Snape wasn't a sign of her being a bad friend but rather that their interests no longer clashed as he was studying something that Lily despised. They just grew apart over time, and that was no fault of Lily's.
Towards the end of The Deathly Hallows, we learn Snape apologised later on. Unsurprisingly, Lily didn't forgive him and severed their friendship permanently.
He'd have a hard time convincing his Death Eater friends not to kill her and she'd spend a lot of time hanging around with people who'd discriminate against her blood status. They could potentially have a child, but Snape doesn't seem like the person who'd want one to me. So I'd assume they'd have a childless marriage.
"The first thing Snape asks Harry is "Potter! What would I get if I added powdered root of asphodel to an infusion of wormwood?" According to Victorian Flower Language, asphodel is a type of lily meaning 'My regrets follow you to the grave' and wormwood means 'absence' and also typically symbolised bitter sorrow.
One reason Snape doesn't want to reveal his love for Lily is his intensely private nature. Having others sentimentalize his feelings would cheapen them. He also wouldn't want to be object of pity.
According to the books, he didn't. He was a lonely child who could speak to no one until he found another child he could speak with. The few times we see their interactions they interact as friends, and it's clear that Sev loved his friend. Not so clear that Lily, in spite of her promises, loved him in any way.
Later, Snape tries to apologize for calling Lily a Mudblood, but she's not interested; she ends their friendship due to his association with Death Eaters. Seventh Year: James becomes Head Boy and seems nice enough now for Lily to start dating him.
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.
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.
In the Harry Potter series, why didn't Lily marry Snape? The simple answer: She didn't love him. The more complicated answer: He proved again and again that he wasn't willing to listen to Lily, respect her or her views, or love her in a healthy way.
Snape, in his insults directed to her, always called her an insufferable know-it-all and targeted her intelligence, but maybe she was insufferable to him because she constantly reminded him of Lily and her know-it-all habits.
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.
That's right! You heard me- their daughter. For those unaware, in the Cursed Child (which was written for a POST Harry Potter world)- it's revealed that at one point in time, Bellatrix and Voldemort conceived a child of their own- Delphini.
Bellatrix used a powerful "love potion" on Voldemort and they have sex while he is temporarily obsessed with her. She then uses obliviate on him while he sleeps (you know, he falls asleep after his post-sex cigarette) and tells everyone that the baby is her and her husband's.
But the author also told The Leaky Cauldron's "PotterCast" podcast in 2007 that Voldemort tried to recruit Muggle-born Lily Potter, along with James, to join the group. She said it was established in "Harry Potter and the Sorcerer's Stone" that, "He wanted them, and they wouldn't come over."
