"Oi, Snivellus."
Severus, who was standing at the sink in the bathroom, looked up and saw Potter's angry face in the mirror. He turned and faced the insolent boy. "Yes, Potter?" His voice was calm, modulated.
"These little cozy library sessions you've been having with Lily have to stop. Now."
"Potter, I am certain that you are aware that we have been assisgned a joint project by Professor Slughorn." Severus paused. "Oh, do forgive me. I tend to forget that you are not familiar with him, due to the fact that you weren't...capable of ascending to NEWT level Potions. I know how much it must have pained you to have been able to share a cauldron with dear Lily."
Potter took out his wand, but not before Severus had.
"So she's Lily now, is she, Snivellus? Whatever happened to 'Mudblood Evans', then? She may have forgotten, she may be all...friendly with you now, but I haven't. You're a Muggle-hater and you love the Dark Arts. Do you honestly think she could ever care for you?"
"That is a question you must direct to her, Potter. The only conversations that we have are ones that concern our research. If not for this project, I would not deign to spend time interacting with anyone outside of my House. Just as you fraternise with your fellow Gryffindors."
Potter laughed snidely. "Except I never see you with any Slytherins. You always have that greasy nose in a book. Ever since Malfoy graduated, you've been quite alone, haven't you?"
Severus smirked. "I'm flattered that you feel I deserve so much of your observation. Perhaps if you stopped lavishing such attention on the males of Hogwarts, you might have already been with Lily by now."
Potter looked to be on verge of jinxing Severus when Professor Slughorn entered the bathroom.
"Ah, I thought I heard voices in here," the portly man exclaimed. "Mr. Snape, would you please accompany me to my office? I wish to discuss some matters with you." He inclined his head politely in Potter's direction. "I do apologise for tearing you away from your friend here." He clapped a hand on Severus' shoulder and steered him out of the bathroom, leaving Potter behind looking severely wrong-footed.
Severus smirked at him over his shoulder as they exited.
