Katherine knew it was a bad idea. She really didn't care but it was a bad idea. She stepped into Bucky's bedroom, looking around. The man was asleep in his bed on his back. She made sure to be silent as she walked over to the man. She gently grabbed his right hand and closed one part of the handcuffs she was holding around it. She waited for a moment to make sure the man didn't wake up before she leaned over him slightly and grabbed his left hand, bringing it up and as quietly as she could, closing it around the metal. She smiled to herself as she left the room, making her way back to hers and Steve's floor.

"Are you serious!?" Bucky said as he came into the 'family' floor. The rest of the Avengers turned from where they sat on the couches and began to laugh when they saw the man. He was still handcuffed together so he couldn't actually put a shirt on or fix his hair before he came to find the other Avengers. "Whose bright idea was this?" He asked as he tried to break the cuffs but they wouldn't budge. They were specially made handcuffs that were able to hold Steve… she knew that Bucky wouldn't be able to break them either. Clint and Tony began laughing while Katherine tried her hardest not to let Bucky see her trying not to laugh. She leaned into Steve side as the man looked down at her. He knew it was her but he didn't say anything, he was going to let it play out as it may.

"Who was it because this is gold!?" Tony asked, finally able to breath. Bucky rolled his eyes and tried to pull the cuffs apart again.

"It wasn't me." Clint said, whipping a tear from his eyes.

"I don't give a damn who it was as long as they come off… now." Bucky said, glaring at everyone in the room. Katherine sighed, clearing her throat as she began to look for the key in her pockets. Her brow furrowed when she didn't feel it. She got up and walked past the bound man as she went to the elevator, maybe the key was in their room…

"Well, I have some bad news." Katherine said as she stepped out of the elevator. Bucky had now settled on the couch beside Steve in the spot that she had vacated, looking at the handcuffs hard enough that he was hoping they would just melt off. He did look up at her when she walked in.

"What's that?" He asked. She bit her lip.

"Well… I can't find the key." She said, shrugging her shoulders.

"You can't find the key?" He asked, raising an eyebrow at her.

"Nope. I have no idea where it is." She said, trying to smile. The man closed his eyes and sighed.

"That's fine." He said, pulling frantically at the cuffs for a moment before he stopped and sighed. "Do any of you girls have a bobby pin?" He asked and Natasha scoffed.

"There is no way you're getting out of those with a bobby pin." She said, crossing her arms over her chest.

"Get me one and I'll prove you wrong." He said, smirking at the redhead. Wanda reached into her hair and pulled out a pin. She reached over the coffee table to hand it to Bucky. The man offered Wanda a smile before he began trying to pick the lock on the cuffs open. All of the Avengers were watching the man and after three minutes, he smiled in triumph as his metal arm slid free of the cuffs. "Tada!" He said, giving them all jazz hands with his now free hand.

"Well, I'm thoroughly impressed." Katherine said with a raised eyebrow. Bucky switched the bobby pin to his metal hand as he opened up the other side. When the lock was opened, the cuffs fell to the ground. He handed the bobby pin back to Wanda before picking up the cuffs and turning his attention to Katherine. She raised an eyebrow at him before taking a step back, she was happy she was still standing up at that point.

"James Buchanan Barnes… if you even think that you're going to put those on me you are sadly mistaken." Bucky stood up slowly as an evil smile spread across his face. Any other time, Katherine would have been admiring the fact that the man moves like a cat, so easily and graceful but at the moment, his sights were set on her. "Steve…" She said to the man. He leaned back against the couch, watching his best friend and girlfriend.

"You brought this on yourself." He said before Bucky's smirk got bigger and Katherine's eyes got wider.

"Thanks babe. Love you." She said before turning and running down the hall. Bucky jumped onto the coffee table and then over the second couch before taking off after her. The rest of the Avengers listened as there was a squeaking squeal before a crash. They all looked down the hall before Katherine came back into the living room. She jumped from the one couch to the coffee table to the other couch before running into the kitchen, Bucky came running through a moment later.

"Hold still!" They heard him say to her.

"Never!" She replied. There was a smaller crash before Katherine ran back down the hall, Bucky right on her heels.

"You're not going to help her, are you?" Clint asked while looked at Steve. The other man shook his head with a fond smile on his face. There was another crash and this time they could hear Katherine laughing.
