A/N: Bonus chapter! To make up for my lateness. Enjoy;)

As the kids woke up from their naps, I got a message from Pepper saying that Dad was on his way to the base. So, after getting dressed and collecting the giggling masses of twins from their nursery, the three of us went to the kitchen, in search of food. Bucky was making silly faces as the kids

I noticed Wanda and Bruce talking in the lab. I didn't think much of it, until I saw Bruce turning slightly green. Breaking away from Steve and Bucky, I took Callie into the lab to find Wanda trying to apologize to Bruce for something. Her eyes were sparking red and he was glaring at her. But as I stepped nearer to Bruce to talk him down, he roared and pushed me back. Hard. But after what felt like a full minute, I fell onto my back, cradling my sweet girl to my chest.

"God, I really can't take anymore hits today," I moaned, feeling my head for any damage. None, okay. Looking up, I saw that I was in the lab still. So, I was wondering where everyone was. I was used to waking up from a major injury to my husbands around me.

"Mama!" I heard a small voice say, and I noticed Callie clinging onto me.

"Hey babycakes. Where'd your Daddies go? I figured they would be all over us for getting hurt again. Overprotective cinnamon rolls." I teased, looking her over. It seemed like she was uninjured, except for a small cut on her forehead.

"ARSENAL, where is everyone?" I asked, confused as I kissed Callie's boo boo. Wanda and Bruce were just here, where did they go?

"Intruder alert." I heard FRIDAY's voice say.

"Whoa. Dad, I said you couldn't put FRIDAY here. Two AI's is confusing enough," I sighed, trying to pick myself up off the floor, and then picking up my little girl.

"Stand down, and state your reasons for being here," I heard Vision say. Turning and squinting, I noticed Vision hovering over me.

"Vis, what are you talking about? It's me, Sera." I said, holding Callie tighter.

"I do not know you. Now, I ask again, who are you and what is your business here?" Vision stated, head inclined in threat.

"Vision, where is my Dad? He should have been here by now." I said, not understanding his threatening posture.

"I do not know who your father is."

"Uh, yes you do. He helped create you. Tony Stark? Doesn't that mean something?"

"Shall I contact Mr. Stark?" FRIDAY said.

"Hold that please." Vision said, noticing my confusion. His head inclined again, looking deep into my eyes and I wondered what was going through that android head of his.

"Vision, are you malfunctioning?" I asked, scared that Ultron's original programing was winning the fight for control of the andriod.

"You do resemble Mr. Stark. But he has no known children." Vision said.

"What are you talking about? I'm Sera Stark. Well, it's Rogers-Barnes now, but I'm still a Stark. Vision, do you not remember me?"

"Out of the whole planet, no Sarah Stark exists." FRIDAY's voice said suddenly.

"How are you spelling my name? It's Seraphina. S-e-r-a-"

"Vision, you just disappeared. Do I suck at Chess or some-" Rhodey's voice stopped when he noticed me. I turned to my uncle, only to be shocked by the robotic exoskeleton on his lower half.

"Rhodey, did Fitz build you those? It looks like my Dad's tech. Wait, why do you have them? A new lining for the suit?" I said, looking closer at the robotic legs.

"Who are you and how did you get in this building?" His Colonel voice demanded.

"Rhodey, it's me, Sera. Sera Stark?" I asked, feeling annoyed. They were all playing a prank on me. It had to be that, as Callie started to whimper.

"I don't know you, and you are definitely not a Stark."

"Seraphina Stark does not exist." FRIDAY responded.

"Where's Steve? This isn't funny anymore guys!" I yelled to whoever was hiding.

"FRIDAY, call Tony." Rhodey said to the ceiling.

"FRIDAY, where are Bruce and Wanda?" I asked, panicking.

"Dr. Banner's location is unknown, as is Wanda Maximoff's."

"Where is Pietro? Guys, this really isn't funny anymore. Where are Steve and Bucky? Where is Elijah?" I screamed, feeling a panic attack controlling my lungs.

"Pietro Maximoff died in Sokovia, after receiving multiple bullet wounds. Captain Rogers and Bucky Barnes are fugitives, location unknown." Vision supplied.

"Mr. Stark is on his way down. I told him it was urgent." FRIDAY said, but my hearing was fading as I felt myself struggle to breath. They looked unsure of me, but Vision also looked concerned. Pulling up a chair for me, he sat me down gently, as I felt the tears start. Callie stood next to my chair

"Who's this?" I heard softly, as I struggled to calm my breathing.

"She claims to be Sera Stark, your daughter." Rhodey said, as I looked up to see my father, looking worn and heartbroken.

"Oh my god," He said, stumbling back in shock.

"What? Is she?" Rhodey asked, as I gasped.

"Rhodey, she… she looks… I can't..." Tony said before abruptly leaving the room.

"This isn't funny anymore," I said, hugging my daughter to my chest.

"Facial analysis confirms a 53% match with Mr. Stark."

"Then why did Tony run out like that?" Rhodey asked FRIDAY, "Who's her mother?"

"I… can't… breathe." I said softly before I felt myself pass out.


"She's coming around." I heard as I tried to open my eyes.

"..Hugh?" I asked as I awoke to Natasha's Black Widow face.

"Who are you?"

"Nat? Where's Callie?" I asked.

"Who are you?"

"Damn. You're in on this too? I'm Sera! Siren? The nickname I hate doesn't ring any bells?"

"I do not know a Sera."

"Come on Nat. I can tell you anything you want. I know about the birthmark under your left butt cheek. I know Clint's family farm location off by heart. Lila and Cooper, and little Nathaniel are my godchildren!"

"How could you possibly know any of that?"

"BECAUSE! I've been here since my father announced himself Iron Man. I infiltrated Stark Industries on Fury's orders. I know he's alive too. SHIELD was infiltrated by HYDRA back in the 50's and Steve found out, ending SHIELD, but Coulson brought it back a few years ago on Fury's orders, making him Director. InHumans are real, Clint's favorite arrow is the exploding ones, because he's a secret pyro. You loved Clint after he brought you to SHIELD, and it wasn't until after New York, where the Chitauri invaded Earth, that he told you about Laura and the kids. Steve was found in the Arctic Circle in March of 2012 and we battled the Chitauri in June of 2012."

"Internet. SHIELD files are readily available now."

"Does SHIELD have record of your birthmarks though? Scars that already existed on your body? Say the scar in the form of teeth marks on your right shoulder blade given to you by Sasha in the Red Room?"

Her silence was everything. Looking out the window, I expected to see crisp leaves changing color, but all I saw was snow.

"Natasha, what day is it?" I asked, horrified.

"December 20th, 2016."

I felt my heart drop, as I whispered, "No."

"That's not possible." I sighed, wanting to wake up from this nightmare.

"I just had my birthday two weeks ago. It should be October 19th," I said to myself. Callie was on the floor next to me, playing with a small block of wood, and a doll. I assumed they were from Clint's kids.

"It's not possible. Wanda's powers must have done this, right?" I whispered to myself.

"I need to talk to Steve. Please!" I pleaded with Natasha.

"How do you know Steve?" A voice asked, and I turned to see my father in the doorway.

"He's my husband. Him, and Bucky. This can't be new to you guys?" I asked, confused as to why everyone was acting like I was the enemy.

"I'm going to need you to calm down. What can we call you?" Natasha asked.

"Sera," I pleaded.

"Do you have an actual last name? And one that isn't Stark, Rogers or Barnes?" She asked.

"Kalashnikov? Nash for short." I said, feeling a stab of pain as Tony's eyes narrowed.

"This really isn't funny now. How dare you come here and use her name, like it's nothing more than a ploy for money." He said, enraged.

"Excuse me? That is my last name, and has been up until the point where you asked me to take your last name. Dad, you have to believ-"

"I don't. Ana died in a car crash on… on the same day Barnes killed my parents, only a year later. She died pregnant with my only child."

"She… NO! She died 8 years ago, from cancer. This is wrong! Nothing makes sense!" I said, feeling myself start to panic again.

"Her brainwaves indicate no deceit. She's telling the truth." FRIDAY said softly.

"Just because you believe something, doesn't mean that it's true." Tony said.

"Tony," Nat said as I hugged my knees to my chest.

"I need air," I said, tearing out of the room and towards the balcony after scooping Callie into my arms. Ripping my long sleeve off to reveal my tank top, I felt calmer as my wings grew from my back. Sighing in relief and grabbing Callie's whimpering form, I stepped up to where I could jump off the balcony, stopped by a sudden arm around my waist.

"Are you one of Xavier's freaks?" Dad said and his words stung, as he pushed me down to the floor.

"No, I'm InHuman. My mother was too, but she never went through the transformation to get her powers." I explained, feeling the tears leaking out of my eyes as I saw a glowing gauntlet stretched over his hand, pointed at my face.

"Please, I can show you!" I screamed, as Natasha restrained me, and he took Callie from my arms.

"What do you want here?"

"I want to be home. I can show you. Just please don't hurt my daughter," I said, retracting my wings and raising my hands in self-defense.

"I think I stumbled into an alternate reality. If you are two months ahead of my time, and I do not exist here, the only logical explanation is that this is not my dimension." I said, slowly and heart wrenchingly putting the clues together.

"Dimensional travelling? The only thing close to that is the Bifrost."

"Once you eliminate the impossible, whatever remains, no matter how improbable, must be the truth. Sherlock Holmes."

"Miss Kalahnikov's theory could prove correct." Vision said, speaking up. Dad looked at the android hard, before saying, "I know we haven't discovered it yet."

"We may not have, but in her timeline, things could be more advanced. The statistical probability of multiple universes is exponential. I detected an anomaly in the lab after we removed Miss Kalashnikov, and it appeared to be Wanda's power signature."

"She couldn't have come back to the country, let alone the base. She knows that we were working for Ross and the UN."

"No, it was an echo of her powers. They seemed stronger than I've ever known them to be." Vision said.

"I've been helping her gain control over her powers. She's stronger because her emotions are clear. I taught her to dance, and Brock taught her how to love."

"Rumlow?"

"He's my cousin. Nikolai Kalashnikov. Oh right. That's the other thing you don't know."

"Rumlow is dead." Natasha said, breaking my heart just a little further. She started to loosen her grip on me as Dad – or his other dimensional self- released my daughter. She looked confused as to why Grandpa didn't want to hold her, but ran to me for comfort.

"So, you killed him. My only biological family other than Da- Tony. Sorry." I said, trying to gain my own control.

"No, Wanda did." She said and I had to fight back tears.

"Wait, you said you work for Ross and the UN? Why?" I said confused, after I shoved the pain down where I would deal with it later.

"The Sokovian Accords. The UN wanted control of the Avengers after all the trouble we caused. New York, DC, Sokovia, and Lagos."

"Wait, nothing happened in Lagos. I absorbed the blast from Ajax's bomb." I said, shaking my head.

"The bomb in Lagos was strapped to Rumlow's chest, intended to take out Steve. Wanda contained it, but ended up blowing up a few floors on a building, which jump started the need for the Accords."

"But, we saved the day. I mean, I ended up with radiation burns for a few hours, but nothing happened. It was literally a few hours ago for me." I said, "So, what did the Accords entail?"

"A leash for the Avengers. One that was controlled by the UN. More specifically Ross."

"General Ross? The one that Fury had me keep an eye on due to his attempt to make a second Hulk? Or his want for more super soldiers. Like Hydra?" I deadpanned, and Tony pulled back as if burned.

"Okay, okay, I know. Ross, bad guy, Tony stupid for trusting him." He said, sass ever present. I took a deep breath, realizing a majority of the team was missing.

"Where are Steve and Bucky really?" I asked, as Callie whimpered at the sound of her Daddies' name.

And I was sorry I did.
