A/N: So I have three chapters for you today. I'm pleased to say I've written about 32 in total, and hopefully I'll have a better understanding of how to continue when CA:CW comes out. For now, enjoy!

Disclaimer: I do not own Marvel, Disney, The Avengers or ABC. Just Sera :)


"Ms. Stark, pleasure to meet you." The doctor said as she entered, outstretching her hand for me.

"You as well Dr. Mandel." I replied.

"I will repeat again, how important I value my patients security. Your file was put under a Jane Doe, as not to draw attention from my staff. I was thankful you came in incognito. I will ask you to do so every time, as some of my staff members still like to gossip, with patients in the waiting room to overhear."

"Understood. Thank you for your discretion," Steve said, taking his Captain's pose behind me.

"It is something I value; the safety and comfort of my patients and their families. None of your information will leave my safe. It will not be recorded in the computer, and if you request, all your files can be sent back to Stark Tower in an armored truck if need be. This won't get out if you don't want it too." She said, reassuring me that I made the right choice.

"Now, I will personally do the work up myself," She laughed, as she pulled on a pair of gloves.

"Guys," I asked quietly.

"Do we want to know whose it is?" I asked quietly.

"We don't know what kind of effects the serum could have had on Bucky, and we don't know if it can be passed down or not through me." Steve said, taking Bucky's hand.

"Not that I won't love this child if it's not mine, but I would like to know. Not for pride's sake, but for how our altered DNA will affect the little one's growth." Bucky said, voice unwavering.

"That's very noble," Dr. Mandel said, smiling over at us.

"If we can, can we do a paternity test then," I said, as Steve squeezed my shoulder in support.

"Of course. We may have to wait until you are farther along." She said, taking the transducer in one hand and the ultrasound jelly in another, "You know the drill. Up with the shirt, and wiggle the pants down two inches."

Doing as she asked, I nearly jumped at the cold gel hitting my bare skin.

"Sorry. Now, let's see if we can find a heart beat first." She adjusted her grip, slowly moving the transducer around, as she hit a few buttons on the keyboard underneath the screen. A fast thrumming filled the air, making my eyes water.

"That is your babies heartbeat," She said, smiling before furrowing her brow.

"Is something wrong?" Bucky asked.

"The heart beat is either really fast or…" She trailed off, as she tried to get a better look at my uterus.

"That makes more sense," She sighed, turning the screen and pointing to the box she had highlighted.

"There they are." She whispered.

"They?" Steve, Bucky and I said in unison.

"Two separate sacs, which indicates they aren't going to be identical twins." She said, trying to get a better look.

"I'd say they were both around 12 weeks. We are past the first trimester Sera." I was still reeling.

"Twins?" I whispered. I had been wondering why my clothes were a little more snug then usual.

"We can do the paternity test today." She explained, getting a better picture of the two little blobs that had stolen our hearts.

"Now, to be sure, I'm going to test both babies. I can give you the samples to conduct your own testing on. I won't know the genetic markers for the serums you say you both have."

"I can get Banner to look at them later this week, to see if they were affected." I said, looking at both men. They were staring in shock at the needle she was about to put into my belly. Using the ultrasound wand, she lined up the perfect spot to put it through my skin.

"I can get both babies from this angle," She explained, prepping my skin for the insertion. I had felt worse pain from gunshots, but it was still scary seeing a needle being put through your belly, especially when it was to draw blood from your babies.

"I'll only take enough for each sample, and not a drop more. They still need all the blood they can get." I watched as she carefully put the needle into one of the twins umbilical cords. I laid my head back to look at Steve and Bucky. Kissing my temples, they grabbed my hands in support.

"Annnd done," Dr. Mandel said, pulling the needle from my stomach. Placing a bandage over the hole, she said, "I will need samples from both of you gentlemen. Only a couple drops."

Steve and Bucky were reluctant at first, that much I could tell. Giving them a nod they allowed the good doctor to take some blood.

"I will personally test these right here," She said pointing to the lab in the corner. It was a few minutes of machines beeping, and her moving around, and looking under microscopes. But a final beep made us all hold our breath.

Sighing, she gave a small laugh, "Well, this is a first for me."

"Is something wrong with the babies?" Steve asked, rubbing my belly.

"First, do you guys want to know the sexes?" She asked, smiling.

"I would," I whispered, looking to the guys.

"Please," Bucky asked Steve.

"Yes," Steve said, looking worried.

"This is a rare case. I've never encountered this before, but not so rare that it hasn't happened. Your babies are what we call heteroparental superfecundation. It's when two babies are conceived from two different fathers." She said smiling as we all stared in confusion.

"Both of you," she pointed at Steve and Bucky, "have one child growing inside. They share an egg, but not placenta. They will be half siblings."

"Oooooh," I said, understanding.

"So we each have a child," Bucky said, trying to wrap his head around this.

"From what the testing told me, Steve is the father of Baby A, and Bucky is the father of Baby B."

"And the sexes?" I asked, anxiously.

"Baby A is a boy and Baby B is a girl." She said, pointing to the picture on the screen.

"A boy and a girl," I said, rubbing my belly.

"So, pictures?" Dr. Mandel asked.


"So, give me a second to think this through. You three are in a relationship, and both of you knocked up my daughter, coincidentally with a rare set of twins. And, you expect me to be okay about this?" My father asked in a flat, even tone.

"Yes," Bucky said confidently.

"We are going to skip over the fact that it was the Winter Soldier that killed my parents, because I believe people can change. And the fact that one of the most infuriating honorable men I know, has been sleeping with my daughter for well over a year and has not popped that question he asked me about… 6 months ago." My dad said, arms folded and his eyes hard.

"You were gonna ask?" I questioned, tears welling up. Damn hormones.

"Tony," Steve started, until my father, unsurprisingly, cut him off.

"I have only one stipulation about being okay with this. Because I would rather be in my daughter's and grandchildren's lives than be the father that didn't accept her for who she loves," He said, causing us all to hold our breath.

"Do you at least plan on having some sort of wedding ceremony thing? Make it official?" My father said, sighing in exasperation. My jaw dropped as Bucky and Steve said, "Of course."

"Steve and I had been talking about it. And now with the twins, we should get a jumpstart on that."

"We were gonna sit Sera down later this week actually," Steve said rubbing the back of his head.

"Does anyone think about what I want?" I said, standing up from the couch.

"What if I had no desire to be married?" I growled, "I'm not some breakable doll that needs everyone to make decisions for her. I am an adult, and will not stand here listening to a bunch of pigheaded men make life choices for me."

Leaving the room, I knew I had a limited time frame. They would give me space, for maybe an hour, and then would try to talk me down. I was having none of that today. Making my way down to our floor, I grabbed an empty bag from the hall closet and began throwing clothes in. It was a rushed packing job, but the cash I had in my wallet would be enough to get me where I wanted to go. Taking my burner phone out from the hidden safe in the wall, I stashed my actual phone in there. It would be a wake up call when they tried to find me.

"Hey, I need a place to lay low." I spoke as the other line answered.

"You need a ride?" The voice asked.

"Coordinates. I've got a ride," I said, thinking about my most recent purchase and overhaul.

"The Playground. You know," The voice said, a smirk in their tone.

"Another of Fury's secret bases I designed." I laughed, entering the elevator.

"We'll see you soon….. Agent Stark."

"Jarvis, if you tell them I'm leaving, I will make certain you sound like a girl for the rest of your existence," I threatened the AI.

"Yes Ma'am," he answered back.


A/N: Two more for this week :)
