Isabella pulled up to the Stark/Avengers Tower. She refused to call it anything, but Stark Tower since it had been Tony's baby. "God I don't think I missed this place." Isabella said as she grabbed her bags to get out.

"You missed your team though Izzy. You can't deny that." Bucky said, grabbing his bags as well.

"I guess that's true." She sighed. "You ready?"

"No." Bucky responded honestly. "We have to though, for you."

Isabella kissed Bucky on the cheek. "I love you."

"I love you too." He smiled. "Let's go."

As they walked into the tower, all eyes were on them. "Ms. Stark." The security guard said. Isabella nodded at him as he let them through. His eyes never leaving Bucky.

They entered the elevator and were greeted by Tony's Jarvis. "Hello Ms. Stark."

"Jarvis, you can call me Mrs. Barnes again." Isabella's statement caused Bucky to smile.

"Of course Mrs. Barnes. Where would you like me to take you?" Jarvis asked.

"To wherever Captain Rogers is." She instructed.

"I'm sorry miss, but he's not in right now." Isabella looked at Bucky confused.

"Is Tony?"

"I'm sorry, but none of the Avengers are in."

"Why the hell am I here then?" Isabella yelled. The elevator gave a jerk as it started to go up at a rapid pace. "This feels like a trap." The doors opened and Bucky and Isabella got into a fighting stance.

"At ease soldiers." A familiar voice said.

Isabella relaxed. "Fury. A warning next time would be nice."

"Would you really have come?" Nick gave her the eye. There was silence as he studied Isabella and Bucky. "I'm guess you're disappointed to see me alive." He directed as Bucky.

"Actually, I'm some what relieved to be honest." Bucky relaxed. "I'm no longer what Hydra molded me to be. I have my own thoughts."

"I know that. If Isabella here trusts you, you must be your old self." Fury said. "Now, on to pressing matters. Let's go Mrs. Barnes." Isabella smirked once Fury turned his back on them.

"Where are we going?" Isabella asked as she followed Fury.

"Have you heard of Fitz, Simmons?" Fury led them into a lab.

"Yeah, you put them on Coulson's secret team. I worked with them a few times. I really like them, and that Sky chick." Isabella turned to Bucky. "The Avengers can't know Coulson is alive by the way. Kind of like people can't know Fury is."

"Anyways, I had them help Stark and Banner make you this antidote. It's how I'm getting Tony to fund the secret SHIELD that's up and running." Isabella looked around the lab, and noticed a door that she knew led to a room that was strong enough to hold an Asgardian. "Yes, you're going in there to control what may be side effects."

"Yay me." Isabella said sarcastically.

"Izzy you don't have to do this alone." Bucky said trying to reassure her.

"Buck I have to go in there alone. I almost killed us just last week." Isabella sighed. "I need to get these powers under control. It's not like I'm going to die. The only person smarter than those four is-"

"Her." Fury said.

"Why didn't you do this yourself then?" Bucky asked confused.

"I tried, but-"

"Isabella here kept getting frustrated and destroying things." Fury cut her off again.

"Stop doing that." Isabella said frustrated. "He's right though. When I lose my temper... things break."

"Things freeze, catch fire, the ground cracks..." Fury continued.

"He gets the point."

"I'm glad I haven't pissed you off." Bucky said softly.

"Yet." Isabella smiled. "Alright, I'm doing this, but why is no one here to monitor me?"

"Fitz, Simmons will be here in 60 seconds. Tony is on his way as well. This means I have to go. Also, be patient with Fitz. A hydra agent did some serious damage to him." Fury walked away from them. "And remember, I'm dead."

Isabella turned to Bucky. "I'll be okay." She smiles reassuringly at him. "I promise."

"I just don't want to lose you after I just got you back."

Isabella laughed. "I'm not going to die Buck. I'll be okay." Bucky kissed Isabella with all the passion he could muster up. Their session was interrupted by a small cough. They pulled away to find Jemma, and Sky staring at them. "Where's Fitz?"

Sky and Jemma awkwardly looked at each other. "Fitz currently doesn't have the ability to watch over this injection." Jemma said sadly.

"Well then, it's good to see you two. Sky, love the new hair." Isabella said with a smile. Sky just nodded. She watched Bucky closely. Jemma was taking him in too. "You guys, this is my husband, Bucky Barnes."

"Wait, like, the Bucky Barnes?" Sky asked surprised. "I thought you died in like the 40's. You were on the wall of Valor and everything."

"What's that?" Bucky asked confused.

"We'll talk about it later." Isabella said. "Can we start this? I feel myself getting twitchy." Gemma nodded.

"Let's get you set up."

Isabella was strapped to a bed with an IV filled with blue liquid, and a million monitors. "I don't know about this." She said to the camera they were using to monitor her.

"You're doing okay so far." Gemma said through the speaker.

Isabella closed her eyes as her skin started to burn suddenly. "Fuck!" She said before she started screaming.

"You have to get her out!" Bucky said in horror as he watched and listened to Isabel writhing in pain.

"We can't. Not until the full treatment is done. If we only do this half way she could die." Gemma said studying the thermo tv.

"Her temperate is elevating quickly." Sky said.

"Well my aunt can set herself and everyone near her on fire, so it's probably normal." Tony said as he walked in. "Sorry we're late."

"Oh my goodness. Mr. Stark, I wasn't aware you'd be here for this." Gemma looked like she was star struck. Fitz and her had talked to Tony via phone before, but she had never met the billionaire in person.

"Well Isabella is an Avenger. None of us would miss it." Steve piped in. Bucky stiffened as he saw his childhood best friend. Their last encounter wasn't the best.

"Holy shit you're Captain America." Sky said.

"Guys this is really starting to hurt!" Isabella yelled.

"I thought it's been hurting this hole time." Tony said through the speaker.

"Were you monitoring me you little shit?!"

"Yes captain obvious. I'm always monitoring you, just like you're always monitoring me."

"God I hate you." Isabella said out of breath. "Is Bruce here to help?! I can't take this anymore."

"I'm right here." Bruce came walking in with a syringe. "Ms. Simmons, please open the door." She did as she was told.

"Banner, are you sure you should be the one to go in there? You could possibly Hulk out if she hurts you." Steve said.

"I'm also the only one who would live if something
goes wrong as she's getting this injection." Bruce said.

"I shall do it then." Thor said walking in.

"Oh my goodness." Sky's mouth dropped. "He is really dreamy."

"You're not going near my wife." Bucky said.

"Not now Buck." Steve said.

"Guys!" Isabella yelled as everything started to shake.

"I'll do it." Clint said grabbing the syringe from Bruce as he walked in. He looked at Isabella who was swearing uncontrollably. "Hang in there." He said as he emptied the syringe into her IV.

"Clint, you need to run and shut that door now!" Isabella yelled as she started turning red. Clint got the hint, and ran out quickly as Gemma shut the door behind him.

Isabella thought she was going to catch fire to everything when she suddenly got cold and dizzy. Everything stopped shaking.

"What did you give her?" Bucky asked as he stepped closer to the screen. Her temperature dropped dramatically.

"It's just a sedative." Bruce said studying all the monitors. "Isabella is reacting as well as to be expected to the antidote."

"Well?" Bucky was somewhat irritated by the comment. "She was screaming in pain. How is that well?"

"Buck-" Steve tried to intervene.

"No Steve, this isn't okay." Bucky ran a hand through his hair.

"No, Isabella isn't okay." Tony said. "While you were a frozen puppet for Hydra my father spent the rest of his life trying to find a cure for her. When she woke up she destroyed more than you could possibly imagine on accident. This antidote was her last choice Barnes. We all put our blood and sweat into it. So, yes, this is as well as could be expected. She's alive, we're alive. We can't ask for much more than that at this point."

Bucky clinched his jaw as he imagined himself beating the shit out of Tony. As he was about to retort there was suddenly a loud beeping noise as Isabella flat lined.

"Dr Simmons." Bruce said as Gemma opened the door and they entered the room.

"Izzy!" Bucky yelled as he went to enter the room as well.

"Buck, don't!" Steve said grabbing his arm. "Let them do their job."

"It's Izzy Steve!" Bucky yelled.

"I know it is! Let them do their job. If you get in the way we could both lose her." Steve said as calmly as he could.

Bucky sighed and waited. Listening hoping the peeping would stop.

It didn't though. The beeping never seemed to stop.
