Note from author: I have no idea where this is going right now. I just thought of the idea yesterday and decided to give it a shot. It's probably been written before...I have never written any Marvel characters before, so it may be clumsy. I also have issues with updating frequently, so beware. But otherwise, please let me know if this is even worth continuing. Thanks!
"Put on your suit. Let's go a few rounds."
"He's a stupid, arrogant, selfish boy," Steve thought angrily. "He thinks his toys can protect him, can make him important. He is nothing, he is an empty shell hidden behind an elaborate façade. Millionaire, playboy, philanthropist? Yes, and a fool. A fool like Fury, who thought that bringing him here was a good idea. Doctor Banner knows what he's doing, and Stark just plants dissent among us."
"But he was right about S.H.I.E.L.D.," a small voice whispered in his head. "He was right all along." Steve shook his head to shut the voice off. His rage was building up inside of him ever since Tony Stark "welcomed" him during his mission to capture Loki. And the tense atmosphere in Banner's lab was not helping his self-control. Everybody was screaming and pointing at each other, accusations made left and right. Steve knew he needed to watch Banner, to make sure he didn't…but he couldn't turn away from Stark.
"Put on your suit!" Captain exclaimed.
"Yes," Tony nodded struggling to his feet. There was fire all around them, metal shards peeling away from the walls and raining down on them as they staggered down the hall. Tony felt Captain's arm around his waist helping him stand. He tensed but brushed it off in his hurry to get to the Iron Man. Tony was angry, angry with Fury for lying to them, angry with Banner for not believing him in the first place, angry with Natasha for siding with Captain, and angry with Captain…because he was right. He was nothing without his suit. But he couldn't allow them to know that. Tony wanted desperately to throw some accusatory remark at Rogers for his troubles, but he knew there was no time for that.
And yet…
"There goes keeping Banner in a stable environment. At least it wasn't my fault this time," Tony muttered under his breath. He couldn't help it. Before he could blink away his smug grin, Captain pinned him against the wall with his elbow at his throat to prevent him from getting away. "How dare you…" he exhaled.
Anger was pounding violently inside Steve Rogers' skull. Was that how Banner felt before he turned? Steve Rogers had always been the one to maintain perfect control of any critical situation and to keep his head where others lost theirs. But somehow, Tony had threatened his core balance and triggered such rage as Steve didn't know he had. Even now, with Hulk on the loose and with Loki's minions attacking the ship, he just couldn't hold his tongue. Steve felt a sudden urge to punch that smug expression off Tony's face. He would fight back, Captain knew, and that would compromise their safety and the safety of everyone aboard this ship. But Steve couldn't just let it go. He's gone too far this time. He took a series of shallow breaths trying to clear his head. Tony was smiling, smiling even now…And then, compelled by an impulse as sudden as his previous fit of rage, Steve leaned in closer to Tony's face and planted a kiss on his lips letting all the anger in his veins flow through his mouth into his, hoping in that brief instance to convey his pain, his annoyance, his…surprise.
What was he doing? Steve pulled away a mere second after he started. He stepped away from Stark letting the man sink to the floor to regain the breath he undoubtedly lacked with Steve's elbow at his throat.
"So this is what it was about then…" Tony muttered.
Steve didn't know how to reply to that, so he just turned away smoothing the fallen strands of hair back into place.
"Get your suit and meet me outside," he finally managed before rushing off.
