The Avenger dozing off at afternoon. Tony take the whole coffee table for the nap. Clint hanging at the vent. Typical bird. Natasha take the single couch for herself. Steve and Thor take the other two double couch and Bruce take the whole bar table for himself. The afternoon is so peacefull untilled a loud noise like baby crying in the room.
"JARVIS stop the alarm. It hurting my ear" Tony yelling.
"Shut up Stark. I'm trying to sleep here. Shut the alarm or I will shoot it!" Natasha yelling at Tony.
"JARVIS stop it before I reprogramme you with girl voices" Tony threatening his A.I.
"Sir, it not our alarm. So, I couldn't turn it off. Sir, it not..." JARVIS replied and at the same time the noise is gone.
"What... Ugh.. Nevermind. It already stop" Tony cut JARVIS and continuing his afternoon nap.
An hour later, Natasha, Bruce, Steve and Thor leave the room. Clint still in the vent, sleep peacefully and Tony move to the one of double couch. Then, Pepper coming with some paper sort of report for Tony to check and sign.
"Tony, I need you to..." Pepper stop. She couldn't believe what she see. She see a tiny cutest black haired and bluish sea green eyes that poking into Tony's face.
"Pepper... Stop poking my face. I know you want second round" Tony mumbling in his sleep. Pepper groan a bit. She pick up the baby. "Pepper... There... It good..." Tony continuing sleeptalking which earned the solid, powerful and hardest smacking from Pepper Potts. "OUCH... IT HHHHHUUUUUURRRRRTTTT!!!!!!!!!!!!!!!!!!" Tony histerical scream fill the tower. He wake up only to find angry Pepper Potts hugging a baby. Wait a baby?
"What happen? Who it that? You, Tony?" Clint pop his head through the vent. He see Tony rubbing his head and angry Pepper Potts hugging a baby. Wait a baby?
"Care to explain this?" Pepper shove Tony's face with the baby.
"What? Last time I check no baby at the Tower and I swear I don't know any of us would be asigns as babysitter. That yours Pepper?" Tony's question earn him a Pepper second smack to his head.
"Tony, I found this baby poking your face while you are sleeping at the couch. Do the baby your?" Pepper questioning him.
"Not mine. Completely not mine" Tony replied Pepper and observe the baby closely. The baby smile and cooing at Tony.
"Da... Da... Da.. Dada" the baby babble to Tony.
"Tony, are you sure the baby not your? To me the baby like you a lot. Like fond you so much like you are the father" Clint asked and observe the baby too.
"Barton, please... My days as playboy been pass. It been three year, I only devoted myself to love the lady over here. Beside, with all the Avenger and SHIELD mission, I don't have time to flirt with other woman beside Pepper. More likely if I'm having a kid sure it only from Pepper" Tony defend himself. "Can you hold the baby Pepper? Arguing will not help, but the baby DNA will speak clearly to us" He added. He handed the baby to Pepper and the baby babbling to Pepper while Tony take the blood painless. He immediately run the test.
"Mama" The baby babble to Pepper.
"Do you two heard it? The baby call me Mama. Oh isn't it cute. Tony look. This little one will going to be my new sweetheart" Pepper amaze by the baby act. Tony feel jelous to the baby already.
"Uoo...Oh... Somebody jelous..." Clint see how Tony act. "By the way we can't call the baby The Baby and the gender too. Let see who the winner is... Oh congratulation, it a boy" Clint comfirm the baby is a boy.
"Awww isn't he cute..." The Baby already win Pepper's heart. She then see a bottle of wine scattered at the floor near the bar. "Who scatter these wine bottle? Hmmm..." Pepper stop as she see The Baby giggling to her which give her an idea to name him. Wine... No what name close to wine syllable? Oh... Wayne... And she smirking. "Wayne.." The Baby giggling and cooing. "You like it, don't you, Wayne..." The Baby continuing the cute giggling. "Tony, meet Wayne" as Pepper hold the baby gentlely.
"You name him already and you name him based on wine bottle" Tony replied.
"Tony, I think Wayne is his given name" Clint replied.
"Clint might right about it" Pepper add. At the same time, the test result finished.
"Sir, the test is done" JARVIS cut the scene.
"Show me, JARVIS. I think your little prince will need to say bye bye, Pepper" Tony replied.
"Sir, the baby is your" as soon JARVIS announce it Tony happy face gone.
"JARVIS what do you mean by he mine?" Tony panicked. Pepper and Clint glare at him.
"Half of his DNA is match your, Sir" Tony jaw dropped.
"Stark, I thought he not your. Care to explain?" Clint asked.
"He really not mine" Tony try to defend himself.
"By the way Sir, half of his DNA also match with Miss Potts too" JARVIS added.
What JARVIS tell the three of them, make them handle with a huge serious matter because it mean that the little Wayne is Tony and Pepper's. It weird as she never give birth to any infant, even pregnant with one either.
"What? JARVIS there is mistake. I mean... There no..." Tony speechless like Pepper and Clint. Three of them just shock.
"There no mistake in fact, the test been processed for four time" JARVIS continuing.
Pepper sit in silence and Tony is speechless for a while and Clint just stare at Tony, Pepper and the little Wayne. Tony stand up.
"We do like this untill we figure what is going on. The baby will spend time with me and Pepper, without anyone know about this. I will set up a floor for the baby which will be our new Penthouse. You, legolas shut your mouth. Zip it tightly and if can stitch it. Clear?" Tony suggest a temporary solution.
"Ok with me" Clint replied.
"Are you sure Tony? I mean hiding him" Pepper doubting about hiding Wayne from the other.
"Pepper it only a temporary. If you want to show off him to the other, just let me deal with the legal term. Make him officially Stark's. You going to spent time with him and I will deal the company. We take turn to be with him. Sound reasonable?" Tony deal to Pepper.
"Ok, I trust you on this. Let do it, just do it" Pepper replied with a bit confident.
That day passing with Tony and Clint set up the new floor with baby proof, baby crib at the bedroom with other baby stutf. It took a while but no one know about the moving as the other penthouse still retain by Tony. After done, Clint climb back to the vent and go to his spot earlier which he hop down and sit next to Natasha. He pretend that it never happen.
Meanwhile, Tony settle the checking of baby proof. Pepper just done bathing Wayne and set up his diaper, powder him, and wear him a cute baby pyjamas. After dinner, Pepper feeding Wayne with formula milk and burp him, Pepper put him to sleep by humming to Wayne softly. Tony just done bathing amazed with the beautiful scenery infront of him. The first night is quite smooth as Wayne only wake once at 04:00 a.m and then sleep again.
The next morning, Tony and Pepper already awake but they thought Wayne just a dream. They only realize when both of them see sleeping Wayne in the crib.
"Pepper, you know we should be married" Tony said it to Pepper. She gasp but then smile.
"You asking me to marry you" Pepper guessing.
""So... Yes or... No?" Tony pop the question.
"Awww...Tony. Of course it a yes. YES!" Pepper without doubt answer yes to Tony.
