How do you move on with nothing left?

In wakanda:

"Steve?" Bucky said gently as he looked at his hand in horror as he watched it disappear before his very eyes.

Steve walked over to his friend not knowing what to do, but he was too late. Bucky was gone. Steve turned around and saw so many of the avengers tuning to dust. Groot. T'challa. Wanda. Sam. And so many more.

Captain Rogers couldn't pull himself together. He was in so much shock. The Avengers had lost the war. Thanos had won. Now half the universe paid for their mistake.

On Titan:

Everyone stared in shock to where Mantis had been standing moments before but now all that remained were scattered pieces of ash on the ground. 
"Quill?" Asked Drax as he too turned to dust.

They then noticed that Quill was swaying slightly. "Oh shi-" but his cuss was cut short when he turned to dust.

Four remained; doctor strange, Tony Stark, Peter Parker and Nebula.
"It was the only way" whispered doctor strange before he peacefully turned to nothing.

"W-what just h-happened" stuttered Peter Parker as he struggled immensely not to cry of fear and shock.
"We lost" replied Tony simply.

At that moment Tony accepted his defeat and fell to the ground. Nebula went to a near by broken down ship and began pulling it apart clearly trying figure out how to get off this bastard of a planet.  Moments later Peter sat down next to Tony.

"You okay, kid?" He asked quietly.
Peter just shook his head and closed his eyes. Tony was never very good at being comforting or showing sympathy but he could see the kid clearly needed something, so he just hugged him and Peter (a little shocked from the action at first)hugged him back and that was when the tears came. Both of them were crying in each others arms but all Tony could think about was how he had failed. He had failed the Avengers. He had failed the world. He had failed the entire universe. He had failed himself. He had failed Pepper. He had failed Peter. He had failed. Big time.

Peter pulled out of the hug, "are you okay mr. Stark?" Both Tony and Peter knew it was just a question to be polite because no body would be okay.
"I'm sorry" said Peter as tears pricked his eyes again.
Tony looked over at the teen extremely shocked to what he had just said. The poor kid had just witnessed death beyond anything and he APOLOGISED?!! He loved this kid so much but sometimes he just wished he knew what he was thinking.
"Why are you sorry?" Tony asked "you didn't do anything wrong"
"Yeah I did, if I had just stayed in the bus with my class then maybe you wouldn't have been distracted and could've beaten Thanos and save the universe" he started to cry again but only softly and tears began to crawl down his cheeks "if I had just stayed on the bus then.... maybe half the universe would still be alive." He looked away from Tony not wanting Ironman to see him cry. But Tony saw right through him and pulled him into a side hug. "NONE of this was your fault, okay? Absolutely none of it, if it weren't for you I would probably be dead right now." At this point Tony was holding his shoulders and shaking him slightly. Peter then broke into sobs  and was struggling to sit up straight so Tony pulled him into another hug and Tony played with Peters hair while telling him "shh it's okay, I'm here, I'll never leave you."

Little did they know that Nebula had been watching the whole thing with wide eyes and even a slight smile spread across her face to see the two with such a connection.
"I really hate to interrupt but I got a ship started so we should probably leave now so that we get back before you die of thirst and starvation." Both Peter felt a little uncomfortable knowing that she had been standing there just watching them.

Nebula led the way to the ship and all three of them were eager to get back to earth....well at least what was left of it.

He ship was rather roomy but not luxurious in any way. Once they got the ship up and running and left Titan Peter was absolutely amazed at the view of stars and constellations and far off planets of all different sizes. For the first twenty minutes of the trip it was silent but not awkward it was just quiet.

After about half an hour Tony noticed Peter sitting in the corner  curled up into a ball with his head resting in his arms, if it weren't for the heavy breathing and occasional sniffle then Tony would have thought that he was asleep, but he was not sleeping, it was quite clear he was crying. Tony sat down next to Peter and put his hand on his back, Peter jumped a little at his touch but still didn't look up, Tony continued rubbing his back and his breathing became less sharp but the sniffling slightly continued. After a few minutes he looked up and Tony had never seen a face that looked more in pain, his face was wet with tears and his eyes were red and puffy.
"It's alright buddy, we're going home" Tony said softly
Peter didn't say anything, he just looked at Tony with straight fear in his eyes. Fear that they wouldn't make it home. Fear that May, Ned and everyone he cared about would be gone. Fear he wouldn't ever see those people again. Fear that he would die alone. Fear that he had failed. Fear that he would be able to move on.
