You got it, thanks for the prompt!

“Tony?” Bruce whispered as he slipped into their bedroom, far later than he intended after losing track of time while working on a particular equation. But the room was dark, void of the comforting, characteristic blue light from Tony’s arc reactor. The arc reactor that kept him alive, that was always visible as a reminder that behind it, Tony’s heart was beating steady and strong. 

“Tony?” Bruce asked again, a little louder and a little more worried, greeted by the muffled groans and mumbles of his beloved. 

“Brucie?” Tony mumbled, and Bruce felt his heart skip a beat. Was Tony okay? Was his arc reactor out? Was he struggling to speak? Why didn’t Jarvis say anything? 

“Jarvis, lights,” Bruce said, stumbling over to the bed and to Tony’s side, just as the lights came on. Tony rolled to his back, his hand up to shield the lights from his eyes. 

“Hey, what the fuck,” Tony said, fully awake now, and Bruce sat on the edge of the bed and held him by the shoulders. 

“Tony! Are you okay? Your arc reactor, it’s-“ Bruce started, but as he spoke, Tony reached into his tank top, pulling out a piece of flat, black plastic, immediately revealing the glow of his arc reactor through the thin fabric. “What?” Bruce asked in confusion. 

Tony chuckled, relaxing back into the pillows.

“I made a cover for it, I thought the light was keeping you up. They say blue light stimulates the brain and makes it hard to sleep. I’m used to it, but I thought-“ Tony said, handing the cover to Bruce to see. Bruce sighed, sagging in relief. 

“I thought something was wrong, that it stopped working and you- you-“ Bruce said quietly, and Tony sat back up, realizing Bruce’s worry.

“No, no, god, I’m sorry, I should have told you first. No, sweetheart, I’m fine. Just sleeping is all,” Tony reassured Bruce, and pulled him into a hug. “I’m okay. I promise,” he whispered, and Bruce buried his face in the crook of Tony’s neck. 

“Don’t cover it. Please. I like the light, it’s… comforting,” Bruce said softly, and Tony kissed his shoulder. 

“I won’t. Come to bed, love. I’ll keep you up all night with my obnoxious blue flashlight, and you can complain to me in the morning,” Tony said, kissing Bruce’s relived smile as they crawled back in bed together. 

Yay! I wrote you a very Avengers circa 2012 post-battle reunion ficlet. Thanks for the prompt!

“Okay, SHIELD is on site, containment is underway. Everyone back at the Quinjet- ow, Hulk!” Steve yelped, falling hard on his ass as Hulk poked him in the chest. His earpiece fell out, and he scowled, scrambling to put it back in, only to hear Clint laughing both over the comm line and in real life as he approached the Quinjet. 

“All right Big Guy, quit beating up on Cap,” Clint said, swatting Hulk’s arm lightly. Hulk huffed. 

“Where’s Tinman?” he rumbled, and Clint sat heavily on the ground beside Steve, wiping at the sweat and grime on his arms uselessly. 

“I’m sure he’s on his way,” Clint said, and Steve sighed, tapping the earpiece. 

“Iron Man, report in, please. Your greener half is impatient,” Steve said with a weary sigh. This was an increasingly common post-battle conversation, with Hulk pacing until Tony arrived back safe. Usually, Tony had a quip or a laugh, and would talk to Steve over the comms as he flew back, so Hulk could hear and not freak out. 

This time there was silence. 

“Iron Man, report,” Steve said again, catching Clint’s gaze with some worry. No response again, and Hulk now knew something was wrong. “Black Widow, report,” Steve said.

“Haven’t seen him since he flew behind the line,” Natasha said, even as she jogged toward the Quinjet. Just then, Thor landed heavily beside Hulk, his hammer slowing its spin. 

“Aye, he has been unusually quiet,” Thor said, spinning Mjolnir again as though to go in search of Tony, but he paused when they all heard the characteristic whine of a repulsor charging, then blasting through some rubble up the street. 

“Tinman!” Hulk shouted, and then Tony walked gracelessly through a pile of concrete, his armor unwieldly and more suited for flying than walking over rough terrain. 

“Hey there, Green Bean,” Tony said, coughing as the facemask lifted. “My boot jets are offline, I can’t fly.” Tony’s mouth was curved into a mischievous sort of smile that was enough reassure the others that all was well, despite the fact that Tony usually hid his pain better than a cat. 

Hulk closed the distance between Tony and him in a leap, and picked Tony up into a hug, carrying him back to the Quinjet like an unruly child. Tony laughed, pushing at his broad green chest. 

“All right, put me down, this is ridiculous,” he said, but Hulk didn’t. In fact, the smile on his face matched Tony’s, and he didn’t set Tony down until they were back at the Quinjet and Bruce was beginning to take over for Hulk. 

Tony held both of Hulk’s hands as they shifted back to Bruce’s small hands, dwarfed by Tony’s gauntlets. 

“There you are,” Tony said softly, looking at Bruce as though no one else in the world existed. 

“You didn’t answer your comms,” Bruce said, but his tone was equally soft, as he laced his fingers with Tony’s. 

“Got fried in a blast. I’m fine, just had to walk back,” Tony said reassuringly. “Sorry to worry you, Green Bean.”

Bruce smiled fully then, closing his eyes and touching his forehead to Tony’s. 

“Now now, you know worrying is my favorite pastime,” Bruce murmured, getting a soft laugh out of Tony. Then they both jumped as a pair of pants flew through the air and hit them both in the head. 

“I know you have no shame, Bruce, but this is the third time this week we’ve all seen your ass. I think you could try a little harder at saving that privilege for Tony,” Clint said, rolling his eyes. Tony just winked at him. 

“I could show my ass too if you want to even it out a little,” Tony suggested, and Bruce laughed, wrapping his arms around Tony’s neck and kissing him, a soft, warm press of lips that carried a thousand silent “I love you’s” in it, then pulled away and put on the pants. Tony sighed dramatically when Bruce’s ass was finally hidden from view. 

“Imagine seeing an ass like that and insisting it be covered up. Unbelievable,” Tony muttered, and Bruce’s cheeks went pink. 

“Tony,” he said, clearly a little flustered, and Tony just took his hand again, squeezing it. 

“I know, you love me, I love you, let’s go have victory sex in the Quinjet,” he said.

“Tony!” said everyone else. 

I feel like doing a little writing tonight, if anyone wants to drop me a prompt and get a lil ficlet in return!
