Why didn't Hagrid know that Harry was alive when Voldemort told him to carry him back to Hogwarts? Firstly, he was overwhelmed with emotion. He didn't think about checking the pulse. Secondly, Harry was considerably small with respect to Hagrid.
After Harry's apparent death at the Dark Lord's hands, Hagrid was forced to carry his body back to the castle, sobbing and crying non-stop, devastated over the loss of Harry.
Like most people, Hagrid didn't know that Tom Riddle was Voldemort. Therefore, he really didn't need to know or care that much about Riddle besides what happened to get Hagrid expelled.
Narcissa Malfoy, married to a Death Eater, lied to Lord Voldemort and made him believe Harry was dead. However, it wasn't true, as she could feel the pulse of the Boy Who Lived. This courageous act from Narcissa also allowed Harry to survive this moment.
On confirming Draco's very much alive status, she plainly lied that Harry Potter was "dead". This action of hers was both very crucial and important, not only for Harry's survival but for Voldemort's final defeat as well, thus ensuring Harry was again protected by a mother's love, although indirectly.

Why did Narcissa divorce Lucius?
In fact, Lucius' own support to Voldemort is revealed to come only under some form of duress, which is likely Narcissa's Veela Allure. When Lucius turns on Voldemort due to the reveal of his Horcruxes, Narcissa divorces him, taking 75% of Malfoy's wealth with her.
Something that people get wrong about Narcissa Malfoy is that she was a Death Eater, when in fact she was never part of Voldemort's inner circle of believers. She certainly affiliated with the Dark Lord's side, but her maternal side won over her evil one when she had to check if Harry was still alive in the Forest.
'Is Draco alive? Is he in the castle? ' The whisper was barely audible; her lips were an inch from his ear, her head bent so low that her long hair shielded his face from the onlookers.
However, there were a select few that had his trust, and whom he treated with respect. This included Bellatrix Lestrange and Severus Snape. No matter what Snape did as a spy, Voldemort never figured out he was not on the Dark Lord's side.
A doe. And in his final battle with Lord Voldemort, Harry explained the significance of this to his adversary, and to us: 'Snape's Patronus was a doe,' said Harry, 'the same as my mother's, because he loved her for nearly all of his life, from the time when they were children'.
He is closely associated with the Order of the Phoenix, and has explicitly denied the anti-Muggle/Muggle-born ideology of the Death Eaters. There is quite literally NO plausible way Hagrid could be or ever have been a Death Eater.
As a result, Hagrid appeared to others as the one who opened the Chamber of Secrets and had released the monster who lived within it. Therefore, Hagrid was expelled from Hogwarts and his wand was broken by others. This meant he wasn't allowed to complete his education and become a wizard.
At the beginning of the Battle of Hogwarts, the Death Eaters invaded the home of the Acromantula and drove them to attack the school. When the spiders attacked, Hagrid ran forwards to protect them. Acromantula are horribly strong, so it is likely that they captured him and took him to Lord Voldemort.
Family. Snape's family background is mostly shown in flashbacks during the course of the last three novels. Snape was born to Eileen Prince, a witch, and Tobias Snape, a Muggle, making him a half-blood (hence the name, "Half-Blood Prince").
Under the influence of her father, Dolores grew up despising her mother and brother for their lack of magical abilities. She was sorted into Slytherin House at Hogwarts School of Witchcraft and Wizardry and hated her time at the school due to never being given any positions of power.
She missed Snape, but she knew she could never forgive him. Snape never stopped trying to make amends. But Lily remained steadfast. She could not, would not, forgive him.
But what McGonagall doesn't know is that Snape is actually a double agent working for Dumbledore, so he has no intention of harming her. That being said, Snape holds back quite a bit. Many fans, however, like to speculate who would have won the duel had Snape given it his all.
Notably, Voldemort appeared to be entirely unaware of this split, as he later created a seventh Horcrux in his quest to have six, and continued to target Harry Potter despite him now holding part of Voldemort's own soul.
During this year, Narcissa became pregnant and miscarried. She was distraught and uncertain of what to tell Lucius, as she had not told him of her pregnancy. Shortly thereafter, he brought her out to the Leaky Cauldron to visit with his friends Vettlingar Yaxley and Thorfinn Rowle.
J.K. Rowling says Draco doesn't have a patronus because he never learned the spell but I think it's because he doesn't have any powerful happy memories to use.
This seemed to change around their sixth year, as Draco's mission made him more stressed out, and he lost focus on his usual bullying and abuse of power. By the next year, Draco finally came to a better relationship with Harry, though far from a true friendship.
Narcissa and her husband, Lucius Malfoy, appear to have an affectionate relationship. He gave in to her wishes when she wanted their son to attend Hogwarts, rather than Durmstrang. Narcissa and Lucius both enjoyed being members of the social elite, and loved and spoiled their only child.
He marries Narcissa Black and together they have one son, Draco, who is the first Malfoy family member introduced in the series. The Malfoys are related to the Black family through Narcissa (a first cousin of Sirius Black, Harry's godfather), which makes Draco a nephew of both Bellatrix Lestrange and Andromeda Tonks.
