Bucky hadn't left.
He would never be able to leave Steve again.
He sat frozen, waiting to attack any hydra agents that might find the unconscious Steve. Up in the trees he watched as what he hoped was a shield agent found Steve. The woman called for backup and attempted to stop the bleeding.
It wasn't long before the black widow arrived to help take him away. Bucky remembered her. Not fully but in flashes. The pain of remembering drew a small whimper from his lips.
Her body stiffened, the red hair falling to her shoulders blew in the breeze, but she didn't move a muscle. She knew he was there.
"Are you going to help?" He voice was strong but Bucky heard the note of fear. He was behind her in seconds. Her breath heavy but even as to not cut herself on the knife now at her throat. Natasha. That was her name. How he recognized her he wasn't sure, she had been maybe 16 when he attacked her.
"I was never here." He wasn't sure if she would tell anyone but hoped her fear would be enough. "If you ever notice my presence ignore it."
Bucky didn't wait for her to answer. He returned to his tree and followed Steve's body to the safe house.

Bucky waited for days but Steve still hadn't woken. The need for food and water too strong to resist any longer. He packed up the stolen sniper he used to watch and protect Steve and made his way to the cafe many floors below. The odd tower with a large A on the side that they moved Steve to had been a nightmare to scope. With its tinted windows and many rooms above and he suspected below ground. He had trouble keeping track of possible hydra agents.
The days continued to pass till it had been a week. Even with his discipline the wait had become too much. He had stolen a jacket to cover his arm and left his larger weapons on the roof. He now only had a few knives and a handgun.
Bucky had no plan to use them. Instead he climbed up the edge of the building. For anyone else this wasn't an option and he felt safe he wouldn't encounter anyone. Steve would not be happy if he hurt anyone. Bucky's fingers were bleeding down his arms by the time he reached the balcony. Tumbling over the edge he righted himself less gracefully than most would imagine a re known assassin would. He had no time to waste. Bucky ran to to doors and ripped them open. Again the flashes hit him. This time sending him to the ground. He remembered seeing it on the news. The battle of new york. That was how he recognized Natasha. She had been on the news and the scientists he was guarding had been talking about her.

Lifting his body was easy after the pain had faded. But he had lost time. Running to the elevator he pressed the button repeatedly. He sighed in relief when he found it empty. Taking it to the floor he had calculated Steve to be on the doors opened to a sight that was pure torture. Seeing Steve like this was different than through a scope. From far away he couldn't see the bandages on his torso or the healing cuts on Steve's face. Injuries Bucky had made. The pain of seeing this threw Bucky. Taking a seat and Steve's hand seemed the only logical move, so he did. Bucky's blood left marks on Steve's arm but he couldn't bring himself to care if anyone noticed. His mind was aware of everything but his body could not keep going.

"Steve, please wake up. I can't leave you." To Bucky's surprise Steve stirred. In all his hours of watching he hadn't seen Steve move a muscle.
"Bucky?" Steve's eyes fluttered and Bucky was tempted to hide. He was ashamed to have Steve see him this way. Steve saw his reaction and quickly held Bucky's wrist tighter.
"Till the end of the line." Steve whispered.

This this is my first story so I hope you like it. I wrote this for my best friend.
