Severus Snape Origins Explained (Childhood to Death)

Because Snape was going to kill him, thinking that by killing Snape he would become the true owner of the Elder Wizard, Voldermort shot Nagini towards Snape, who was already hiding around him, making him lose color from his face. Until he said that, Harry took off his invisibility cloak (in the book, not the movie) and looked at the man he hated. Harry found it, eyes widening as he tried to say the memories that were pouring out of Snape, and Harry put them in a bottle. These were the memories that told Harry the truth, the truth that Snape was a triple agent, the truth that he.

He had always been loyal to Dumbledore, the truth was that Harry had to die for Voldermort to be killed. The fact that Snape loved Harry's mother. His green eyes met her black ones. After a moment, something in his black eyes began to fade, and Snape didn't move after that; honestly, Snape was one of Dumbledore's most loyal assistants. The only reason Voldermort didn't suspect him was because she couldn't understand Snape's love (Harry voice)
