The Truth Hurts
Snape held Harry against the wall of the Dungeon corridor, hatered seething from his eyes. "You will NEVER say that to me again," Snape growled. "I loved Lily Evans in a way that an ungrateful brat like yourself can never imagine... Don't you DARE tell me I betrayed her..." Snape released Harry as a pained look settled in. "I already know that much."
"You hated my mother," Harry snapped back. "You called her a mudblood."
"You wouldn't understand Potter," Snape growled. "To think so differently from those you grew up with. to be a constant dissapointment in their eyes. you couldn't understand what thats like. My Mother did everything she could to make sure I behaved "Properly". Including threatening the life of the only person who mattered to me."
Harry's jaw dropped. "My-my mother?"
"The summer after my third year, he told me that unless I severed all ties with Lily Evans, she would suffer a 'Tragic Accident'. So I did so, to protect your mother."
"What about after school?" Harry demanded. Severus was one of the few people who'd known his parents, he was going to push the limits of this as far as he could.
"I realized my... feelings regarding your mother were not hatred, or resentment. far from it in fact. I loved her. sadly she was already married."
"To my father," Harry added.
"Of course." Snape said, sitting at his desk. "To my advantage though, your father had not changed as much as things seemed. soon she left him for a short time, seeking a friend. I was there. she moved back in, but continued to see me. she and I..."
"LIAR!" Harry yelled at him. "My mother wouldn't cheat on my father!"
"And your father would never torment a person for no reason?" Snape countered.
Harry smoldered, his far of anger wasn't quite out.
"We never did anything that required the removal of clothing, if that eases your mind..." Snape felt torn. he wanted to enjoy the anguish he was causing the boy, but this was a story of Lily. "Infact, that is how she knew she had to end thigns with me. You were why she had to end thigns with me."
Harry reeled. him... his mother got pregnant. and that had ended Snape's affair with her.
"So you see, you are at one time the thing that cost me my true love," Snape said, obviously wrapping up his story. "And my last reminder of her. You, or more accurately your eyes, are the last monument to Lily Evans... so if you ever need to worry about wether or not I will harm you, take comfort... I will not rid the world of Lily Evans' blood."
