Harry Potter experienced Severus Snape’s death in real-time. Despite their hatred for each other across seven books and eight films, the duo had some level of respect towards the other. It all concerns Lily Potter, the protagonist’s late mother.
Snape’s last wish is to look into the eyes of the woman he once loved a final time before his death, and Harry Potter can grant that desire, which he does. Before Severus’s demise, Harry and his friends, Hermione Granger and Ron Weasley, manage to take a few memories that verify that their longtime enemy was on their side the entire time.
The fascinating part about Snape’s death is that it should never have happened. Lord Voldemort, in his desperate quest for immortality, murdered his secret agent devotee because he believed that he was the master of the Elder Wand. He gets his secret Horcrux and beloved snake Nagini to attack Snape in the Shrieking Shack and her venom eventually killed him. It is also at this moment that the Dark Lord has no idea Harry is one of his Horcruxes.
In the film Harry Potter and the Deathly Hallows: Part Two, Voldemort attacks Snape in the Hogwarts boathouse by slitting his throat. He then sets Nagini on Snape like he does in the Deathly Hallows book.
In the years after the Battle of Hogwarts, Harry Potter married Ginny Weasley and had three children with her. Their middle child and second son, Albus, was given the middle name Severus in honour of Snape, the man who loved Lily enough to protect her son.
