Bucky came to gradually this time, eyes cracking open at the sound a crackling wrapper. His gaze revealed what looked like a starry night at first, tiny white LED lights sprinkled across the ceiling making him think of the pristine dark skies at the front in WWII when the shelling stopped for a few hours.
Correction, Barnes, you are not in Italy. You are underground with a man who hates you beyond all imagining, he reprimanded himself. The glow was peaceful and calming despite every breath grated his ribs on steel making him want to stop to end the pain. You've been through worse, Buck, he mentally sighed, besides, what would Steve say?
"Ah, you're up." Tony looked casually over at the prone soldier.
Bucky remained silent, conserving his energy.
"Not much for conversation, but I get it." He took a bite of his power bar, "You didn't say much for the last seventy years or so, if I get your history right."
Bucky narrowed his eyes in a frown.
"It's ok." Tony continued munching, "Those bots working for you? You look a bit better." His tone was feigning concern.
Finally, Bucky had enough and gathered enough air to hiss, "Stop with the bullshit."
"Oh, so you want to have an honest conversation down here where we both may be the last people we see on Earth before we run out of air!?" Tony snapped angrily, eyes dangerously dark.
"I got all the time" Bucky swallowed painfully but forcing a snarky smile, "In the world."
Stark sat back and took another angry bite of his energy bar. Several minutes passed as Bucky concentrated on breathing and not passing out again, wondering how much longer he had.
"I am sorry, Tony." It was barely audible.
"I know." Tony couldn't look at him, the honesty was too raw.
"I know I did it." A wheeze escaped him from his collapsed lung, "But I couldn't stop it."
"I know!" The words echoed like a thunder clap.
Bucky, wide eyed and gasping for breath, passed out again.
