Thank you to everyone who has favorited, followed or reviewed this fic so far.

So finally, this is continued to an extent. I think this story will be a little shorter than most of my other ones.

Chapter 3- Messed up

12th January 2014, Triskelion, Washington, D.C.

Steve Rogers, Sam Wilson and Maria Hill had infiltrated the Triskelion's communications room and Rogers had then used the intercom to notify all the employees and agents in the building of Hydra's plot, urging them to stop the launching of the Helicarriers.

HYDRA agent Brock Rumlow ordered the launch be preempted in response, but the technician refused. Agent Sharon Carter pulled her sidearm on Rumlow, who cut her hand with his knife and stole her gun after a tense Mexican Standoff, involving numerous HYDRA and loyal S.H.I.E.L.D. agents. This action caused a shootout between the two factions, during which Rumlow was able to escape. Rogers and Falcon then boarded the Helicarriers as they were beginning their takeoffs.

Meanwhile, in the World Security Council room, Alexander Pierce's identity had been revealed to the other council members due to Rogers' speech. The council members were even more shocked when STRIKE agents loyal to HYDRA filled the room and held them all at gunpoint. Pierce then asked Councilman Singh if he would be so against Project's Insight's true goals if the same methods were used to save his daughter from execution. Singh curtly replied he would, much to Pierce's amusement. When Pierce prepared to shoot him, Councilwoman Hawley suddenly attacked Pierce and his men, single-handedly taking them all down. She then held a shocked Pierce at gunpoint, and revealed herself to be none other than Black Widow in disguise.

While this was happening, Rogers and Wilson managed to replace the targeting blades on two of the three Helicarriers.

"We're the only air support Captain Rogers has got", a S.H.I.E.L.D. agent said as him and some others were walking into their Quinjets to help Rogers and Wilson.

That moment, one of their Quinjets was blasted off by a grenade. As the flames and smoke cleared, the Winter Soldier appeared. He fired another grenade with his M203 Grenade Launcher, destroying another Quinjet.

An agent tried to throw a grenade at him but he fired his Colt M4A1, killing him as the grenade fell down.

Using his enhanced reflexes, he picked up the grenade and threw it into a Quinjet just as it closed. It exploded and killed both the agents inside it.

An agent fired at him but he blocked with his metal arm and punched him so hard with it that his jaw broke, making him fall down. He then kicked the other one so hard that he was sent flying off into another Quinjet. He fell into its rotors, being sliced into pieces while the Quinjet stopped working because of it.

He then climbed on top of another Quinjet as it closed and shot the pilot. He then ripped out its door and sat inside. He threw the body away and started flying the Quinjet upwards. What he did not know was that someone was hanging on to it. It was the Terminator. It had arrived to fulfill its goal.

"Hey Sam!" Steve called out as Hydra agents pointed their weapons at him, "Gonna need a ride!"

"Rogers! Let me know when you're ready!" Sam said via earpiece.

Rogers jumped off the Helicarrier as the Hydra agents fired at him and said, "I just did."

Sam flew towards him and caught him. He struggled to hold him but managed to fly up. The two landed on the final Helicarrier.

"Well, you're a lot heavier than you look", Sam commented.

"I had a big breakfast", Steve said dryly.

Suddenly, the Winter Soldier jumped out of his hiding place and pushed Steve away. He fell off the Helicarrier.

"Steve!" Sam called out as he tried to fly after him but Winter Soldier grabbed his wing and pulled him back.

Sam fired at him with his Steyr SPP pistols but he flipped to avoid. Sam flew to save Steve again but Winter Solider used his grapple device to grab his wing and pulled him down, making him fall. As he tried to get up, Winter Soldier pulled again and the wing was torn off. As Sam got up, Winter Soldier kicked him on the chest, sending him flying off too.

As Sam fell, he managed to detach the other wing from his suit and produced a parachute, landing safely just in time.

"Cap! Cap! I'm in. Are you okay?" he frantically asked Steve via earpiece.

"Yeah, I'm here", Steve replied, "I'm still on the Helicarrier. Where are you?"

"I'm down. The suit's down", Sam said regretfully, "Sorry Cap."

"Don't worry", Steve assured, "I got it."

"Falcon!" Hill's voice came via earpiece.

"Yeah?" he asked.

"Rumlow's headed to the Council", she said.

"I'm on it", he said, deciding to stop Rumlow instead.

Steve ran across the ramp-

Only to see his path blocked by the one person he had hoped not to face. The Winter Soldier! It was none other than his best friend- Bucky Barnes! He had been presumed dead for years. But he was alive. And he had been brainwashed by Hydra into becoming their assassin. He didn't remember anything about his life before becoming Hydra's puppet.

"People are gonna die, Buck", Steve tried to reason with him, "I can't let that happen."

In a cracking voice, he begged, "Please don't make me do this."

The only response he got was a cold glare. Seeing that, Steve's face steeled up. With all his might, he threw his shield.

Bucky deflected it with his metal arm and as Steve caught it again, Bucky fired at him with his Glock 19 and SIG-Sauer P226R.

Steve blocked all the times and managed to push Bucky back but Bucky shot under the shield, getting Steve on the abdomen. Steve grunted in pain.

As Bucky charged, Steve hit him with the shield in a rotator motion, sending him back. Bucky got back up, holding a knife.

Before he could attack though, there was a gunshot and Steve quickly put his shield in the way to block. Even Bucky stopped on hearing that. The two turned to see a tall man of 6 feet 3 inches emerge. He wore a black shirt, brownish trousers and a grey trenchcoat.

In his hand was the Uzi 9mm.

He fired again but Steve blocked and threw his shield at him, sending him flying back. Bucky then attacked him with the knife and Steve blocked. Bucky kicked him on the foot, sending him down. He tried to attack with his metal arm but Steve pushed him back with his shield. He then tried to put the chip but there was another gunshot and Steve ducked. The gunshot hit Bucky on his metal arm.

The two then turned to the tall man again. Steve now realized that this was no normal man as a normal man would not be able to get up so quickly after being hit by his shield. Bucky was human but in his current state of mind, he processed things like a machine too. The tall man's gunshot had hit him and he wasn't Hydra. So Bucky assumed he was a threat.

He pushed Steve out of the way and punched the man hard, making him stagger back. Before he could recover, Bucky kicked him on the knee in a rotatory motion, making him kneel down. Before he could do anything, Steve's shield hit him on the face, sending him flying down.

Steve picked up the chip but that moment, Bucky charged him and the two fell down the railing. Steve's shield fell away. As Steve hit the ground, the chip fell out of his hand.

Steve and Bucky got up and charged each other. Bucky punched Steve on the abdomen with his metal arm. Steve blocked another hit but Bucky smacked him on the face, sending him flying off. The two slid to the edge as Steve grabbed the chip. The two got up at the same time and Bucky smacked Steve's hand, sending the chip down. Steve smacked him on the face and kicked him down before jumping after him.

As he landed, he was grabbed by the tall man and thrown into a corner. As the man advanced on him, Bucky grabbed his foot. The man punched Bucky hard on the face, making him fall back down.

Steve then gave him a flying kick, making him stagger back. He then gave him a flip kick, making him stagger again. He tried to flip kick again but the man grabbed his foot and flipped him to the ground this time. He then took out his Uzi 9mm but Bucky charged him and pushed him off. He punched him on the face repeatedly before the man grabbed his hand and pushed him off before kicking him away. He then got a very strong flying kick from Steve from behind. The kick sent him flying off and he was down.

Steve then ran towards the chip. Bucky picked up his shield and threw it at him, making him fall down. As Steve got up, Bucky fired with his Glock 19 which Steve blocked with his shield. Steve then threw his shield which Bucky deflected with his metal arm as he took out his knife. Steve dodged a slice before trying grabbing his hands. Bucky used all his strength and managed to drive it into Steve's right shoulder, making him shout in pain. Steve then head-butted Bucky twice while Bucky pushed him to a wall.

Steve pulled out the knife and saw Bucky crawling towards the chip. Steve grabbed his arm but he resisted. Steve grabbed his neck and managed to lift him into the air. He then slammed Bucky on the ground and twisted his normal arm in which he was holding the chip.

"Drop it!" Steve commanded as Bucky tried to fight back, "Drop it!"

Steve then twisted his arm and he screamed in pain. Both of them were now on the ground, struggling violently. Steve put Bucky in a chokehold and restrained his metal arm with his foot. Finally, Bucky lost consciousness and the chip fell to the ground. Steve let his unconscious body go and picked up the chip before rushing to put it in.

Steve leapt back up and rushed towards his destination. That moment, there was a gunshot and he was hit on the side. It was the tall man who was up again. Bucky got up too and fired but Steve narrowly avoided as he continued running towards his destination.

Steve climbed up while narrowly avoiding gunshots from both.

"30 seconds, Cap", Hill called out via earpiece.

"Huh", Steve panted in exhaustion and pain, "Stand-by."

He took out the chip but just before he could put it in, a shot from Bucky hit him and he fell down, panting heavily.

The Helicarrier managed to lock onto all of its targets which numbered over 715,000. Tony Stark was one of them. The tall man lowered the gun, knowing the mission was accomplished.

But at the last moment, Steve used his remaining strength to get up and put the chip inside. The targets all disappeared.

"Okay, Cap, get out of there", Hill said to him via earpiece as she made the Helicarriers target each other.

"Fire now!" Steve said.

"But Steve-"

"DO IT!" Steve commanded, "Do it now!"

Reluctantly, Hill pressed the button and the Helicarriers started firing at each other. Steve staggered around to avoid the shots. Some of them destroyed the ground under the tall man and he fell out of the Helicarrier.

That moment, Steve heard Bucky's pained screams and saw that he had been pinned down by a huge piece of debris.

Steve slowly made his way towards him and using all his strength managed to lift the piece of debris long enough for Bucky to crawl out. He then dropped it and the two panted.

"You know me", Steve said to Bucky.

"No I don't!" Bucky said angrily as he punched Steve away.

"Bucky", Steve said with a cracking voice as he got back up, "You've known me your whole life."

Bucky lowered his face, as if remembering. But he looked back up and with a roar, punched Steve away again.

"Your name…..is….James Buchanan Barnes", Steve said.

"SHUT UP!" Bucky yelled as he punched him away again.

As Bucky panted, Steve threw away his mask and said to Bucky, "I'm not gonna fight you."

He then let go of his shield and it fell out of the Helicarrier.

Looking at Bucky with some hope, he said emotionally, "You're my friend."

The two stood still for a while. Suddenly, Bucky roared and rushed Steve, pinning him to the ground.

"You're my mission", he whispered to him before punching him repeatedly with his metal arm, "You're…..my…..mission!"

He stopped and was about to land the final blow.

"Then finish it", Steve whispered hoarsely, "'Cause I'm with you to the end of the line."

The words triggered something as Bucky's face was suddenly full of emotion. He relented, unwilling to throw the final punch.

As he panted, the surface under Steve was shattered by falling debris and he plummeted into the ocean. Bucky watched, his face now full of emotion.

Steve's body was drowning in the ocean when a metal hand reached out to him.

Bucky pulled the unconscious Steve out of the ocean and gently placed him on the nearby land. He looked at Steve as his mind was slowly assaulted by more memories.

He turned around and slowly staggered away, leaving Steve behind.

The Terminator watched the scene, hidden among the trees. It didn't make any move as attacking them was futile now. It had failed to kill Tony this way. Now the only way to kill him was face-to-face. So it walked away.

April 26th, 2025

Steve, Thor, Natasha, Bucky, Banner, Clint, Sam, Rhodes, Wanda and Pietro were sitting around a table, discussing their situation when suddenly Steve and Bucky both grabbed their heads in pain.

"Steven! What's happening?" Thor asked in concern as he put a hand on Steve's shoulder.

"Buck!" Natasha asked as she put her hand on Bucky's shoulder.

The two calmed down after a few seconds.

"What's going on?" Pietro asked them.

Steve and Bucky looked at each other with horrified eyes.

"What?" Rhodes asked.

Looking at him, Steve said, "We messed up."

"What?" Clint asked.

"We messed up really bad", Bucky said.

"How?" Sam asked.

"The machine", Steve said, "It was programmed wrong."

"What're you talking about?" Natasha asked.

"I just got a new memory", Steve said, "One I didn't have before. The machine was trying to fight me and Bucky on the Helicarrier at the Battle at the Triskelion."

"Oh no!" Wanda said as she slowly realized what was happening.

"Why did the machine attack the two of you in that fight?" Rhodes asked.

"I think I know", Natasha said, "One of the targets of the Helicarrier was Tony."

"Oh God!" Steve said in frustration as he slammed his fist on the table, "I told you all this machine was another problem, not a solution."

"The machine was designed to destroy humanity", Wanda said, "So its way of saving is destructive too."

"What do we do now?" Sam asked them.

"There is only one thing that can be done now", Steve said, "I'm going back in time!"

Before anyone could say anything, their alarms blared.

"Oh no!" Bucky said in frustration.

There was a blast and the ground shook.

"Looks like they found us", Thor said as he called Mjolnir from another room.

"So?" Clint asked Steve.

"We fight", Steve said with determination on his face.

Well, I hope my way of moving the plot was fine. This was all I could think of. It will get more intense now.

Please review. I always appreciate your feedback.
