Natasha (who was currently unconscious) was rushed to the Avengers tower where Bruce started to examine her on the now familiar private examination room.

Natasha was struggling to breath so the doctor had no choice but to but her on a ventilator.

Bucky's body was already fighting the poison as his serum was designed to fight things like this.

Tony was removing the bullet from his wound before his body patched itself up.

"I don't know if I have the antidote for her, last time I only just found it but it's not strong enough for the poison I can only treat the symptoms." Bruce said pushing his glasses further up his nose.

"Please Bruce there has to be something you can do!" Steve pleaded.

"Steve trust me I will do everything I can for her but until I find the antidote my options are limited." The doctor explained.

"Maybe I can help." Bucky butted in making everyone in the room stare at him.

"Go on…" Bruce urged placing his hand on his chin.

"Well, if my body is curing it with the Serum, why don't you just take a blood sample from me to see what the red room put in the serum." Bucky continued.

Bruce thought for a second.

"yes, actually that could work." Dr. Banner said and went to get a blood taking kit.

"Buck, are you sure? You hate needles." Steve said, remembering life before the ice.

It was the first time the pair had talked since the hydra takeover.

"Yes I'm sure Steve" Bucky said glancing at Natasha. "I would do it for her." He continued.

Steve nodded and patted his shoulder.

Bruce came over with the injection.

Bucky took a deep breath in and looked at Natasha again before he nodded at Bruce and closed his eyes.

The needle was out seconds after it went in.

Steve patted him on the shoulder again to tell him it was over so Bucky opened his eyes to see Bruce placing a small circle plaster on spot that he had his blood taken from.

Now it was just a waiting game as Bruce analysed the blood to find a cure.

A good four hours went by before he came back into the room that Bucky, Clint and Steve had refused to leave.

The three men looked up as the doctor walked back in.

"I think I have it," Bruce said and he waked to Natasha's bedside.

Bruce quickly took her off the ventilator.

He slowly pushed the needle into her pale skin and watched as the blue liquid ran into her veins.

Seconds later, Natasha gasped for air as she started breathing on her own steadily.

"Okay it may take a few hours to regain consciousness but she should be up to a clean bill of health. However, she needs to stay on bed rest until the twins are born. But the liquid I just gave her is a type of serum like Bucky's in fact she has a more updated version now so I'd watch your title of Captain America Steve as she could be stronger than you and Bucky." The doctor informed them.

The three of them thanked him before he left the room.

Steve knew it wasn't going to be an easy pregnancy from the start but he knew that Natasha was best qualified to do it.

He kissed her forehead and sat in the armchair in attempt to get some sleep, the other two men did the same.

Little did he know the worst was soon to come…

Hiya! Sorry for the lack of updates but I have a lot of exams on at the moment and I unfortunately have to put them first but I will update soon. On a better note the twin's names have been decided so thank you for all your suggestions as I have picked a few of them, the names will be kept a surprise till later when the babies are born so I will give shout outs then. Keep leaving reviews (it lights up my incredible dull days) thanks for reading! C:
