A strange creaking sound began to fill the void, like large furniture being dragged across a floor. Stark looked up as bits of dust and debris came loose from above showering them in grains of sand and grit.
Not thinking, he rose and leaned over Bucky to protect him if any larger bits fell. Barnes was still unconscious and barely hanging on, each breath scarcely perceptible.
Slowly, bit by bit, he could feel the air pressure change and wafts of fresh air being introduced.
"Boss, I think we're being rescued."
"No, I'm being rescued. You are still quite safe in my mainframe." Tony shot back grouchily.
"Just trying to be positive, Boss."
Pin points of light began to seep through, brighter than his tiny LED star lights, and finally a shaft of golden light pierced the darkness and landed on both of them like a haloing spotlight. Tony squinted reflexively as if the light had a pressure although his helmet adjusted automatically.
"Hurry! I can't hold this one for long!" Wanda's strained voice came from above. Tony spared a glance upward, still leaning over Barnes, and there she was hovering the giant piece of concrete with her glowing red mist. The image was like a Renaissance painting with her pulsing red energy. Vision floated down into the chamber ethereally, cape fanning out behind him.
"Tony, you are free to go if you can fly. Do you need assistance?" Vision commented, gesturing to the now open hole above them.
Disbelieving at their rescue, Tony shook his head slightly to snap out of it, "Yeah. Yeah. I can fly." Vision nodded as Stark fired up his boosters and hovered for a moment.
A cloud of dust was kicked up as he ascended.
Vision looked at the fallen former assassin, his readouts telling him he was very close to death. Analyzing the issue of the rebar, he knelt down and used his forehead laser to cut the rebar free just below Bucky's back. Barnes didn't move.
"Hurry Vis!" Wanda called, her breath panting with the effort.
"Coming!" he called, then added to himself, "My love."
Picking up the debris and Barnes in his arms, Vision began to ascend through the space she created.
Tony was standing to the side, Peter pelting him with a million questions, "Are you ok? What happened down there? Did he hurt you? Is this suit working ok? How did you see down there?"
"Parker!" Stark snapped, and Peter shrank back.
"Sorry, Mr. Stark." He looked contrite until he turned his gaze to Vision and Bucky. His mouth fell open and gorge rose in his throat seeing the impaled soldier.
"Bucky!" Steve exclaimed as Vision put him down carefully on the ground. Steve looked up angrily at Stark his mind whirling a million thoughts at him, if they had only moved out of the way of the incoming missile, none of this would have happened!
Vision walked towards Wanda who looked exhausted from shifting several tons of rock with her powers. She glared at Tony from her position.
Stark fidgeted under the judging weight of Wanda's gaze. Widow was darkly somber but her emotions were very close to the surface. Rhodey kept a watchful eye on the two Avenger leaders.
Sam leapt into action, "We need to get him to the quinjet ASAP. There is some of Dr. Cho's first responder tech in there."
"I will take him." Vision gave Wanda's shoulder a gentle squeeze and picked Barnes up again and both he and Sam launched off into the air. Steve gave Stark one more look and took off running in the same direction.
The remaining Avengers stood looking at each other. Tony picked at his helmet with a gloved hand, Parker watching his every move.
"How does it feel?" Natasha asked, her eyes not judging but genuinely asking.
Stark looked at her, a bit of shellshock in his eyes, "What do you mean?"
"Revenge." Wanda interjected. "I lived on revenge for over ten years, Tony. Revenge cost me everything."
Stark appeared to be thinking deeply, "I was wrong for what I let Ross do to you on the Raft. You should be blasting me from here to eternity."
"That means a lot coming from you." Wanda replied, uncrossing her arms, her voice firm, "It's a start."
Tony addressed Natasha's question, "It's not that great."
"But Mr. Stark, he killed your parents." Peter stated thinking of his own Uncle Ben. A part of him still despised those thieves even though everything he had worked on since was for the good of world. He wasn't sure what Tony was talking about with General Ross.
"It's not that simple." Tony explained, "Let's take a walk to the jet. I'll fill you in on my insights."
The five of them moved away from the destroyed bunker towards the quinjet in the distance, calling this mission complete.
