Lily found herself in chains. All around her was death and destruction. Voldemort had won.
"Well my defiant little ginger." Voldemort said in a sickeningly joyful and triumphant tone, "After defying me thrice, you've finally been captured. As a mudblood, you should die or rot." His snake-like face twisted from a prideful grin to an expression Lily couldn't quite make out, "However, I promised Snape that he could have you for a slave if he proved himself worthy of such a reward, which he has."
Lily felt both horrified and relieved. On the one hand, she was glad that her life would be spared and that she would be living with her old friend. On the other, there was a reason she ended her friendship with Snape all those years ago, and who knew how much he had changed over the course of the war?
Voldemort sensed her mixed emotions, then happily sent her to a blank-faced Snape. Lily searched his face for any trace of the boy she once considered her best friend, but couldn't find any.
"Thank you for this reward." Snap replied with a monotone that bore a glint of gratefulness, and to Lily's ears, relief.
Lily was lead to a spacious room inside Riddle Manor, a temporary shelter as more proper accommodations were being made for the top ranking Death Eaters.
As soon as they were alone behind closed doors, and a charm placed over the room to prevent spying, Snape's exterior completely changed. He smiled at her, seeming every bit like the boy who gladly taught her any and all magic he knew without prejudice.
"I'm so glad you're alright!" Snape happily said as he took her bound hands in his free ones. "You have no idea how hard it was to get him to spare you. This was the only way."
Lily blinked back in shock. Becoming a slave to spare her? Was he serious?
"I told you I was sorry." Snape continued, "But no matter what I did, you never accepted it. Hopefully now you can see that I really am sorry, that I never meant to call you that. You're my best friend."
Lily stared at him, trying to process what was going on. Finally, she found her voice. "You fought for and actively sided with pure-blood supremacists who love to torture, took away my freedom, and did who-knows-what in exchange for my life, all in order to show that you aren't a pure-blood supremacist?"
Snape looked nervous, he hadn't exactly planned for her to say that. "Well... yes."
Lily sighed. Same old Sev.
"Lily, please." Snape gently said as he moved his hands up her arms. "This is the only way you can stay alive. I promise I won't be cruel."
"What if the others demand you to?" Lily dared to ask, knowing how he was when the Slytherin gangs pressured him to do stuff in school.
"I'll work around it." Snape promised, "I've come a long way."
Lily glared at him, still unsure.
Snape put his hands on Lily's shoulders, gently gripping them. "Please." Snape begged with a sorrowful tone, "I-I can't lose you. You're my everything. My happiest memory. You're the only reason I can cast a patronus."
Lily pointed an eyebrow. A Death Eater, casting a patronus?
"I can prove it." Snape removed a hand from Lily's shoulder and silently cast the patronus spell. Lily's eyes grew wide as she saw a silver doe dance around the room.
Their patronuses were the same. Which meant either an obsession, or coincidence.
Lily looked at her old friend with wide eyes. Snape met them with gentle and loving ones. After some hesitating, Snape finally said, "I love you Lily, always have, always will."
Lily awoke with a start. That had to be the strangest, scariest, and somehow most beautiful nightmare she had ever had. Voldemort had won, she was a slave. But, she was in good hands.
Lily calmed her breathing and contemplated her dream. Would she really be turned into Snap's slave if captured? She remembered all of Snape's attempts to apologize to her after she had cut ties with him, how he kept trying to impress her in potions, and how he would always praise her. Did he really love her? If he did, that would explain some things. Or maybe, he was just in love with the idea of her.
Either way, if she were captured, she knew life wouldn't be terrible for her. At least if she were given to Snape.
But that was a big "if". Snape might be killed before she could be sent to him, what then? Voldemort certainly wouldn't keep her alive then. And what if Snape lost favor? And of course James, Sirius, Remus, Peter (or so Lily thought), and all her other friends would be done for if captured. She'd be alive, but at what cost? She'd be alone, not seen as a person by all but one, and the only freedom she'd be allowed were what Snape felt was appropriate. Would there come a time when she'd have to force herself to view her old friend in a more romantic light, just to stay alive? Or to ensure good treatment?
"No." Lily thought as she shook her head. She'd never be a slave. She wasn't property, she was a human being. Even if the property thing was only for show, the very idea that she'd be degraded in any way because of who she was, was unacceptable. She'd rather be dead than a slave.
Lily suddenly felt a kick. She gently placed a hand on her swollen belly. Her child would be born soon, and they would be born free. She would love and support them, no matter if they were magical or not. She didn't care if they were a squib, straight, or cis-gendered. They could be intersex or non-binary, and she'd love them the same. Her child would never feel like they had to hide anything from her, nor that there was something wrong with them if they weren't straight or cis-gender. Trans-man or cis-man, they'd be a man to her, and she'd do everything in her power to fight for them. Same if they were a woman.
The door opened, breaking Lily away from her thoughts. Her face smiled as she saw her loving husband come home. She was glad he was safe, and wanted to know everything she missed due to being on maternity leave.
