A/N: Hey, if this is your first time reading one of my stories, hello! If you've read one of my other stories, welcome back! This one is a new one that I've adopted from LucySaxonWrites (go check out her stories). I hope you enjoy it. This one is gen, but if I write a sequel, it may be slash. That way, if you don't like slash, you can read this, but if you like slash you can read it too.

Prologue

Unlike what everyone thought, Snape and Lily were not just best friends. Many people knew Snape was in love with Lily, but not many knew she loved him back. They had started dating at the end of their 4th year. Of course, at the end of their 5th year, they broke up. Lily had a hard time forgiving Snape for what he called her. Once 6th year started, though, they got back together. Lily loved him too much to stay mad at him. After making the grave mistake of becoming a Death Eater, Snape left Lily, never having told her that he joined Voldemort's side. He regretted it, but it couldn't be changed now.

One December night, Snape polyjuiced himself as James Potter just so he could spend one last night with Lily. At this point, Lily was married to James, and she seemed to have forgotten all about him. Snape just wanted one last perfect night with the woman he was in love with, and then he'd leave her alone for the rest of his life. He never expected to get her pregnant, though. After that night with her, he left a note telling the truth of what had happened and an apology. So when it came time for Lily's son to be born, she wasn't so shocked that he looked like Snape. She glamoured Harry and told no one that he wasn't James's son. Snape and the rest of the world were left in the dark, and everyone believed Harry to be James's.

After that fateful Halloween night when James and Lily were murdered, Snape received a letter. He took it from the owl that delivered it and was shocked by the contents.

Dear Severus,

I'm so sorry that I didn't tell you sooner, but I didn't want anyone else to know. I needed to keep him safe. Harry is your son. If you have this letter, then I must be dead. I want you to care for him since James and I aren't there for him. Raise him as your own. Please, Severus. For me. Change his name and keep him safe. He's glamoured, and you'll need to take the charm off. He looks exactly like you, but he's got a mixture of our eyes. Go to Dumbledore with this letter, Severus. He'll know where Harry is, and he'll bring him to you.

And Severus, I've never stopped loving you.

Lily

Snape started to cry. He never in a million years would have expected it. His beloved Lily gave birth to his own son and never told him. He could never hold it against her, though. Following the order in the letter, he floo-ed to Dumbledore's office as soon as the tears stopped falling. He composed himself and stepped out of the fireplace. Albus was sitting at his desk, reading a potion's journal Severus had lent him the day prior. Dumbledore wasn't expecting what happened next. Snape placed the letter on the desk and took a seat.

Dumbledore quickly skimmed the letter, his eyes slowly getting larger and larger. "Oh, Severus," he sighed and stood up. He walked around the desk and gave the Potion's Master a hug. Snape was close to breaking down into more tears, but that wasn't like him so he held them in. "I'll retrieve Harry at once, all right? Just sit here, my boy." With that, Albus floo-ed out of the office. When he got back, he had a small bundle in his arms. The boy looked so much like James, so Albus wondered what he looked like without the glamour.

"Give him here, Albus. I'll remove the glamour," Snape said softly, not wanting to disturb the sleeping boy. Albus handed Harry over, and Snape began chanting the counter-charm. The glamour slowly fell, and Harry began to look more and more like Severus. After Snape was finished, he held what looked like the twin to his younger self.

"He looks just like you, Severus. What are you going to change his name to?" Albus asked.

Snape remembered that Lily had asked for that and thought for a moment. "Alexander, to match his boy-who-lived status, even though I'll try to keep him from finding out until he's older." Albus looked at Snape with a curious expression on his face. "Alexander means 'defender of the people'. As for a middle name, Isamu as a tribute to James and Lily. It means 'courageous'. Even if James wasn't his real father, he took care of him."

"Alexander Isamu Snape. A very nice sounding name, Severus," Dumbledore told him, and nodded. "Certainly befitting of him."

A/N: I hope you liked it. Please review! Also, if you read my other story, you know that I do a question at the end of the chapters. The question today is: What 90's band sang the song "Bad Habit"? Also name one other song from the same album. The reward is an OC of your making showing up in one chapter, or a plot point that you'd like to see being involved.
