How it happened

Steve's pov
Everything was going just fine. It was just another mission. It was routine, nothing more, nothing less. Nothing was out of the ordinary. Tony had been on a solo run with the rest of us as backup. We had left the boys home, with Sam and Bucky, seeing as it was just going to be quick. Then, all of a sudden, we lost all contact with Tony. I was panicking on the inside while trying not to show it. "Tony can you hear me?!" Natasha practically yelled on the intercom. There was no answer we all tried to get in contact with him but couldn't. Everyone but Nat and I had gone down to help and find Tony. It had been a few hours before they came back. I looked at them with hopeful eyes. "I'm sorry Steve we couldn't find him," Pietro said. I finally lost it. The whole flight home I just sat there either crying or muttering to myself. As soon as we landed Bucky, Sam, and the boys were waiting for us. Everyone got off before me and gave Bucky looks. I stepped off the plane and the boys ran to me. "Papa where's dad?" Peter, the youngest, asked me. I picked him up and took Harley's, the oldest, hand. "Pops?" Harley questioned. I gave them a weak smile. "We'll tell you inside," I said as we walked that way.

Pops took us inside with all the other avengers. "Where's dad?" Peter asked again still looking for him. I shifted on my feet I knew something was not right because Pops looks like he's been crying. "Pete." Aunt Nat started. Then I finally, I guess, figured it out. "Pete, I think dad is missing," I said to my little brother. "When is he coming back?" He asked with his big doe eyes starting to water. "I-I don't know Pete," I said my voice shaking a bit. He got out of Pops grip and latched on to me. "Harls." Pops started but it was too late Pete and I both were in tears as we ran to Uncle Bucky. He wrapped his arms around us and gave Pops a sad look. "Steve what are we going to tell the press?" Uncle Clint asked. That was the last thing I heard before I fell asleep.
