3 years later(God that's a big time skip):
Stiles is cooking Bacon when he feels someone tugging on his jeans and a cheerful voice says "Stiwes" . He looks down and smiles "Goodmorning Lia." He picks up the 3 yr old who snuggles to him, her head on his shoulder as Stiles keeps frying the bacon when suddenly when Lia lifts her head and asks something which saddens him "Mama, why am I like this? Why do I turn haily some-times?"
Stiles shuts of the knob and sighs as he sets Lia on the counter sitting her away from stove. He still remembers how shocked he was when on full moon Lia turned into half-wolf asleep. Stiles says hiding the truth "Lia, I understand you feel like you are different. It's because you are a superwoman whose going to fight evil when you grow up." Lia looks at Stiles in awe "Really???" Stiles nods smiling "Yes." Lia squeals and jumps down imitating she's Batman and Stiles knew she got the love for comics from him. He picks her up and says grinning "Now,now young lady. You need to get dressed I am going to drop you at Mrs.Zimmermen." Stiles smiles when Lia runs to her room, he knows how much she loves Mrs. Zimmermen.
He owes her a lot he recalls how scared he was after finding out he was pregnant or when he found out about werewolfs. She is an old warlock who helped him giving birth to Lia.
Stiles is on the toilet sit, the pregnancy test came out positive. He cries, he misses Derek, he misses his dad, he misses everyone that he left behind and now he doesn't understand how he's pregnant.
Stiles is taking the trash out, his neighbour an old lady is also taking her trash out, she smiles at him and he smiles back but it doesn't reach his eyes. She says in her British accent "Sweetheart, are you okay? You eyes are red." Stiles tries dump his trash quickly wanting to go away as fast as he can. "N-No I'm fine." Suddenly, his trash back tears and the pregnancy test comes out with other trash. He looks at Mrs. Zimmermen who is looking at the positive pregnancy test. He stutters trying to form words but his mouth feels dry. Mrs.Zimmermen looks up and Stiles is shocked when he sees that her eyes hold understanding not any disgust or shock. She says smiling sadly "Oh honey, let me make you a tea. It must be hard for you now."
He is brought back from his flashback by Lia tugging at his apron "Mama, I hungry." He sighs fondly "Okay, Okay my little wolf." He picks her up and sets her on the high chair. He fixes himself and her a plate. He places her plate on the table and wraps the bib around her neck. He smiles when she says "Thank you mama." He laughs sadly when she tries gobble the food reminding him of how much she's like Derek. He shakes head to remove these thoughts.
Stiles is running his bag on his head to prevent him from soaking in the rain. He is going to be late if he didn't run more fast. When he is inside the door he sighs in relief. Stiles goes towards the elevator but stops midway and takes a U-turn going behind the wall. He pants heavily, his back to the wall. He looks towards the elevator, his heartbeat racing. He smiles biting his bottom lip when he sees Derek, still looking like an Adonis or better than him. He has some grey hair in his beard making him look more gorgeous than old. Stiles chuckles seeing his eyebrows are still fixed in a frown.
Stiles closes his eyes going back in his position, a tear falling from his eyes. God, he just wants to run to Derek jump in his arms, kiss him like there's no tomorrow. But then he remembers about the woman, his dad and Melissa, he wipes his tears and goes to take another lift.
He sits in his chair and looks around seeing that all the ladies are dressed like they are in party showing too much cleavage with too short skirts. Suddenly, someone screams in his ear "STILES" He jumps yelping and sees his friend laughing "Theo, Stop that"and sits back on his chair. Theo says sorry but Stiles knows from his expression that he clearly does not mean it.
He asks Theo who is perched on the divider "Whats up with the ladies today?" Theo looks at Stiles like he has grown 2nd head "You forgot?" Stiles asks back "What did I forget?" "That we are getting a new CEO today." Stiles eyes go wide eyed when he remembers "Oh shit."
Stiles looks up when someone shouts "He is here." There's a ding of the elevator and the person who steps makes Stiles regret about why is he not late today. He quickly gets down hiding behind the divider thinking why is Derek here and how is he the new CEO? Doesn't he have his own company to run? He looks to the side when Theo whispers to him "Why are we hiding again?" Stiles whispers shouts at him "Why are you hiding?" "Because you were hiding." Saying like its obvious. Stiles groans and says "You don't need to hide. I am searching for something not hiding." Theo looks at him like he understands and gets back up again. Stiles sighs exhausted he sometimes really thinks Theo doesn't understand anything.
Stiles peeks up from the wall, again feeling his heart racing when he sees the love of his life. He gets down when Derek looks at his direction. But what Stiles doesn't know is Derek has already seen him and his wolf is jumping up and down wanting his mate close to him, he growls a little when he only gets a bit of Stiles smell because of all the women's too much perfume, he wants to run towards his mate, embrace him stick his nose near his mark, kiss every inch of him. But he controls himself not wanting anyone to know about Stiles. He is still hurt from when Stiles left him, he plans on how to get Stiles close to him. Because now that he has found his love again, he is not gonna letting him go and he wants answers.
