This was an idea that crossed my mind a few months ago and now I've decided to let it blossom into a full blown story. Lily and Remus had an affair resulting in Lily's pregnancy with Harry. Lily and Remus take drastic measures to hide this from James but one Harry's thirteenth birthday, the truth starts to become revealed in the most terrifying way possible.

Preface

Remus stared at Lily with a look of pure shock and worry; there was no way he could process what Lily had just told him. Remus feared not only for his friendship with James but what this would mean for himself and Lily during a time of war. But what would this mean for the baby?

Of course, the pair knew their actions were wrong but they had simply lost control of themselves one night and now Lily was pregnant with another man's baby.

Remus of course, loved Lily; he'd happily give his life for the kind woman who'd been his first real friend before James, Sirius, and Peter. Up until recently, he'd done so good at keeping his feelings pent up and hidden but that night, they'd been drinking and one thing led to another and...

"Are you sure?" Remus asked Lily once again, knowing perfectly well that her answer was not going to change. James and Lily's relation had been going downhill for several months. James and Lily hadn't been together in such a way for months and even Lily knew this wasn't about to change anytime soon. Everyone knew the reason why James was pulling away from Lily but nobody was going to say anything until James was ready.

But regardless, it was near impossible to tell just how James was going to react to this but at the same time, he had to know because Remus was smart enough to know that Lily would never opt for an abortion. Remus could see it in Lily's eyes; underneath the fear and worry was love for her unborn child. Remus knew in that moment that Lily would give this child everything the world could offer and more.

"I've come up with a plan. It's very drastic but it should work. A spell can be cast once the baby's born so they will resemble James and myself; I've spoken to James about it and he agrees that it is the safest plan for all of us," Lily explained to Remus with a tight smile. "I wish it didn't have to be this way, Remus!"

Lily's green eyes began filling with tears as she looked at Remus but she knew there was no way the two of them could raise a child together. His family would object and James' family would object to the betrayal. Lily knew what James' family was capable of and they had just barely come to accept that James had decided to marry a muggle-born like herself. She shuddered when she thought of what they do when they found out about the baby.

"It's a powerful spell and I will tell the baby the truth when it wears off," Lily informed Remus with a look of pure determination. She didn't want her child to grow up with the stigma associated with being the result of an affair. She wanted more for her child than that and this was the best way to do that.

Remus smiled at Lily with a look of pure adoration and love. He knew if anyone was capable of casting such a spell, it was Lily. Lily was the smartest witch he had ever met and Remus knew she was capable of doing everything her mind deemed possible. Lily stole one last kiss from Remus before whispering.

"The spell should wear off around the baby's thirteenth birthday and that is when I will reveal the truth," Lily said throwing her arms around Lupin in a deep embrace before tearing herself away from him and walking away. She left because she knew if she didn't leave then, that she would never leave at all. She had to put to rest the insane ideas of running off with Remus and raising their child together. The ideas of going with Remus and leaving everything and everyone behind.

Before Remus knew it, Lily was gone and his heart ached for her and now his unborn child. Remus sat down on his living room chair with his head in his hands and fought against the overpowering urge to run after her. Eventually, Remus and Lily would be together with their child; one day.

That was the preface... But things are only going to become complicated from here. Major time skip in the next chapter.
