A/N Hi everyone. I'm sorry I took so long to update this fic. I have no excuse except that I was lazy. For everyone who's been following this fic and waiting patiently, thank you so much and for your support. And now the wait is over and your patience is about to be paid off, so here we go.

As the weeks passed, Oliver continued to make trips to Central City in order to visit his son William. Sometimes Sara accompanied him and sometimes he went alone. Visiting his son regularly was a wonderful experience for him and each visit served to create a strong bond between them, a bond that grew and strengthened as time passed. Eventually, with Samantha's permission, Oliver began taking William out to different places such as the movies, the zoo, the park, and event the ice cream shop. Sometimes he also dropped him off at school and picked him up whenever he was in town, along with other things that needed to be taken care of for the boy, if Samantha was unavailable to do so.

Sara on her part visited Samantha regularly, wanting to get to know the mother of Oliver's child better. The time they spent together allowed them to form a very close relationship and Sara began to see Samantha as a second sister while Samantha saw Sara as the sister she never had. The two women bonded over the fact that they had both fallen for a bad boy, and the same bad boy for that matter, and that they both started off as selfish and immature girls before life transformed them into the strong, selfless women they were today.

Sara also formed a comfortable friendship with William and the boy grew to like her as much as he liked his own father, though he didn't know yet that Oliver was his father. She would also from time to time accompany Oliver and William when they went out to different places and the three of them always managed to have a blast during their outings and the times they spent together. In addition, if neither Samantha nor Oliver were available to take William to or from school, the doctor if he needed a checkup, or whatever else they needed to do for him, Sara stepped in and took care of those things, Samantha eventually giving her the same trust she had given to Oliver. Eventually the time would come when William began to consider Oliver and Sara as his best friends.

One evening, Samantha invited Oliver and Sara to have dinner with her and William, having made a very important decision. They accepted and made their way over there. After dinner, which consisted of linguini, chicken coated with marinara sauce, and delicious warm and toasty garlic bread, followed by a dessert of apple pie and strawberry gelato, Samantha called Oliver and Sara to her and whispered something to them in private. After hearing what she had to say to them, they were filled with great happiness, Oliver especially, having waited for this moment forever. Afterwards, they all approached William and knelt around him.

"William, honey, I, Oliver, and Sara have something very important we wish to tell you", Samantha began, doing her best to hide her nervousness at what she was about to tell her son while hoping he wouldn't react badly, Oliver and Sara also feeling the same way as she did.

"What is it mom?", William asked curiously, wondering what she and his friends had to say to him.

"Remember when you asked me about whom your father was and I said that he was someone I knew a long time ago but we lost touch after I had you?", his mother asked him. He nodded, puzzled as to where she was going with this but intrigued as to the mention of his father. Was he finally about to learn more about him after wondering about him for so long?

"Well William, what I told you was true, but now that's no longer the case. Your father has finally returned to our lives and really wants you to know about him", Samantha answered her son, pausing for a moment as she prepared for what she was about to reveal.

"Really?", the boy asked, surprised but happy that his unknown father had made contact and wanted to get to know him.

"Yes honey. As a matter of fact, he's right here in this room with us."

William's eyes widened at this, and then the weight of his mother's words came down upon him and he turned towards Oliver, amazed yet hopeful as understanding began to dawn on him.

"Are you my dad?", he asked him, really liking this man who befriended him and who he enjoyed hanging out with and hoping beyond hope that he was indeed his long lost father.

Oliver smiled kindly at his son, doing his best to hold back his tears, while also feeling relieved that the truth was about to come out.

"Yes William, I am your dad and I am greatly pleased to have gotten to know you. I am so sorry I wasn't a part of your life but there things going on with me that wouldn't have allowed me to be a good father to you, things I'll explain to you when you're older. But the important thing is that I'm here now and want to continue getting to know you and being here for you, that is, if you want me to?", he answered his son, hoping that he'd say yes but was a little apprehensive and hoped the boy wouldn't reject him now that he knew the truth.

William's mouth dropped open upon hearing his father's confirmation, and after taking a moment to process this news, immediately launched himself into his father's arms.

"Yeah dad, that would be neat and I'm so happy that you're my father.", he answered him while holding onto him tightly, excited that this man before him, who he also considered to be one of his best friends, was really his father. "I really do love my mom but have always wanted a dad too. Now I not only have my mom but also my dad and my best friend Sara. This is awesome."

Oliver's heart swelled with warmth at his son's acceptance of him while Samantha and Sara on their parts were moved to tears of joy at the beautiful sight unfolding before them, all four of them overjoyed that this moment was finally happening while looking forward to whatever the future would bring for them.

The End

[Edited and rewritten AU on 3-6-2020: My original AU on 7-21-16 stated that I was originally going to end with this chapter but decided to add an extra chapter. However I have now decided that this chapter is a good place to end it. At first I was going to probably conclude this with Samantha dying and then Oliver and Sara adopting William. Instead I've removed the cliffhanger and am going to allow Samantha to live and she'll continue raising William but with Oliver and also help from Sara, the four of them forming a happy family. However there's no polyamory here and Oliver's with Sara only while she and Samantha will maintain a sisterly relationship.]
