You went to school with Severus, Lily, James, Remus and Sirius. since the Battle of Hogwarts has started.. Snape had died by the hands of Voldemort and Nagini.

During the battle, you lost another old friend, Remus. It seemed all of your friends from your time in Hogwarts had passed. So when you were in the battle of Hogwarts and found a knife lodged in your side as a last resort from a death Eater, you pulled it out and laid on the ground, taking a few deep breaths. After the war was finished, Harry, Hermione, Ron and the rest of the Weasleys found you, they ran over and tried to stop the bleeding Harry: “it’s gonna be okay!-“ You could hear their voices; Snape, Remus, Sirius, Lily and James.. each of them were telling you it’s time to go on to the afterlife

Snape: “come on you insufferable little..” you could hear Snape cursing your name.. they were waiting for you
