“They sneak out at night

“They sneak out at night. There’s something weird about that Lupin. Where does he keep going?”

“He’s ill,” said Lily. “They say he’s ill – ”

“Every month at the full moon?” said Snape.

“I know your theory,” said Lily, and she sounded cold. “Why are you so obsessed with them anyway? Why do you care what they’re doing at night?”

“I’m just trying to show you they’re not as wonderful as everyone seems to think they are.“

The intensity of his gaze made her blush.

“They don’t use Dark Magic, though.“ She dropped her voice. ”And you’re being really ungrateful. I heard what happened the other night. You went sneaking down that tunnel by the Whomping Willow, and James Potter saved you from whatever’s down there – “

Snape’s whole face contorted and he spluttered, “Saved? Saved? You think he was playing the hero? He was saving his neck and his friends’ too! You’re not going to – I won’t let you – ”

“Let me? Let me?“

Lily’s bright green eyes were slits. Snape backtracked at once.

“I didn’t mean – I just don’t want to see you made a fool of – He fancies you, James Potter fancies you!” The words seemed wrenched from him against his will. “And he’s not…everyone thinks…big Quidditch hero – ” Snape’s bitterness and dislike were rendering him incoherent, and Lily’s eyebrows were traveling farther and farther up her forehead.

“I know James Potter’s an arrogant toerag,“ she said, cutting across Snape. ”I don’t need you to tell me that. But Mulciber’s and Avery’s idea of humor is just evil. Evil, Sev. I don’t understand how you can be friends with them.“

Harry doubted that Snape had even heard her strictures on Mulciber and Avery. The moment she had insulted James Potter, his whole body had relaxed, and as they walked away there was a new spring in Snape’s step…

And the scene dissolved…

Harry watched again as Snape left the Great Hall after sitting his O.W.L. in Defense Against the Dark Arts, watched as he wandered away from the castle and strayed inadvertently close to the place beneath the beech tree where James, Sirius, Lupin, and Pettigrew sat together. But Harry kept his distance this time, because he knew what happened after James had hoisted Severus into the air and taunted him; he knew what had been done and said, and it gave him no pleasure to hear it again… He watched as Lily joined the group and went to Snape’s defense. Distantly he heard Snape shout at her in his humiliation and his fury, the unforgivable word: “Mudblood.”

The scene changed…

“I’m sorry.”

“I’m not interested.”

“I’m sorry!”

“Save your breath”

It was nighttime. Lily, who was wearing a dressing gown, stood with her arms folded in front of the portrait of the Fat Lady, at the entrance to Gryffindor Tower.

“I only came out because Mary told me you were threatening to sleep here.”

“I was. I would have done. I never meant to call you Mudblood, it just – ”

“Slipped out?“ There was no pity in Lily’s voice. ”It’s too late. I’ve made excuses for you for years. None of my friends can understand why I even talk to you. You and your precious little Death Eater friends – you see, you don’t even deny it! You don’t even deny that’s what you’re all aiming to be! You can’t wait to join You-Know-Who, can you?“

He opened his mouth, but closed it without speaking.

“I can’t pretend anymore. You’ve chosen your way, I’ve chosen mine.”

“No – listen, I didn’t mean – ”

“ – to call me Mudblood? But you call everyone of my birth Mudblood, Severus. Why should I be any different?”

He struggled on the verge of speech, but with a contemptuous look she turned and climbed back through the portrait hole…

The corridor dissolved, and the scene took a little longer to reform: Harry seemed to fly through shifting shapes and colors until his surroundings solidified again and he stood on a hilltop, forlorn and cold in the darkness, the wind whistling through the branches of a few leafless trees. The adult Snape was panting, turning on the spot, his wand gripped tightly in his hand, waiting for something or for someone… His fear infected Harry too, even though he knew that he could not be harmed, and he looked over his shoulder, wondering what it was that Snape was waiting for – Then a blinding, jagged jet of white light flew through the air. Harry thought of lightning, but Snape had dropped to his knees and his wand had flown out of his hand.

“Don’t kill me!”

“That was not my intention.”
