Between Thorns And Stars: The space Between

Summary:

A month into their relationship, Tony and Stephen are still learning how to live together.

Chapter 1: December Frost

Chapter Text

 

What Stephen had learned in the last three years about pain was that it never announced itself politely. It didn't send a card saying, "I'll visit you on Thursday, please be ready." It simply arrived, unwelcome and insistent.

This morning, it was his hands.

Stephen stood in the Bloom & Strange warehouse, staring at the roses that needed pruning for Mrs. Patterson's birthday bouquet. His fingers trembled around the handle of the pruning shears—not the slight, almost imperceptible tremor that had become his constant companion, but the kind of tremor that made precision impossible.

He had already dropped the scissors twice.

"Damn it," he murmured, pressing his palms against the work table, trying to stop the spasms through sheer force of concentration. A technique that had never worked, not even once in three years, but hope was stubborn.

The bronze bells above the shop door rang.

Stephen's jaw clenched. He'd forgotten to switch the sign to "Closed." Now he'd have to serve a customer when he could barely hold a pair of scissors.

"Hello?" asked a voice from the front. It wasn't a customer. It was Tony.

Something in Stephen's chest relaxed slightly, only to contract again. Tony couldn't bear to see him like that. A month after the start of this—whatever it was—this relationship, this fledgling thing they were building, Stephen was already showing signs of fragility.

"Here," he called, his voice firmer than his hands.

Tony appeared in the doorway, two cups of coffee in his hands and that smile. He was wearing a dark gray suit that probably cost more than Stephen's monthly rent, looking absurdly out of place among the flowers and soil in the pots.

"I brought offerings of peace," Tony said, raising his glasses. "The usual ones—lots of sugar and a shot of vanilla that you pretend to hate, but definitely don't—and my usual ones—black, bitter, like my soul."

Stephen tried to smile, but at that instant his hands clenched again, knocking a vase dangerously close to the edge of the table.

Tony's expression changed immediately. The playful mask fell away, replaced by something softer and more alert.

"Bad day?", he asked softly, putting down the coffees and approaching.

"Good morning," Stephen corrected, hating the defensive tone he was sounding. "It'll pass."

"When did it start?"

Does it matter?

"Stephen."

That tone—neither demanding nor pleading. Tony had a way of saying his own name that made lying seem impossible.

"Around five o'clock," Stephen admitted. "I woke up and couldn't close my hand."

Tony's eyes darkened with concern. "Did you take something?"

"The prescribed dose of ibuprofen does absolutely nothing." Stephen finally gave up on the scissors, dropping them with more force than necessary. "I'm fine, Tony. I've been dealing with this for three years."

"Managing a situation and being okay are not the same thing."

"I know that, thank you. I was a neurosurgeon, I understand the difference between pain management and—" Stephen cut himself off, noticing the harsh tone in his voice. Pain always irritated him, made him defensive. Another thing he hated. "Sorry. I'm sorry."

Tony approached, carefully holding one of Stephen's hands in his own. His touch was gentle, almost reverent, as if Stephen's bruised hands were something precious, not something broken.

"Don't apologize for being in pain," Tony said. "That's not how it works."

"And how exactly does 'that' work?" The question came out more vulnerable than Stephen intended.

Tony looked at him, his brown eyes serious. "I don't know yet. We're improvising. But I'm almost certain the rules include 'don't pretend everything's okay when it's not'."

Stephen wanted to argue, to insist that he was perfectly capable of dealing with his own problems. But Tony's thumbs traced small circles on his wrists—carefully avoiding the places that hurt the most—and the gesture was so tender that Stephen felt something open up in his chest.

"Mrs. Patterson needs the roses by noon," he said. "Birthday bouquet. Forty-three years. Red roses, baby's breath, eucalyptus."

"I will do it."

Stephen blinked. "What are you going to do?"

"The bouquet. Tell me what to do and I'll do it." Tony was already picking up the scissors, examining them as if they were a particularly interesting piece of technology. "How difficult can it be? You cut the thorns, arrange the flowers nicely, tie a ribbon. I've built several things, I think I can handle some flowers."

"Tony, you don't—"

"I know I don't need it. I want it. Consider this a learning experience. 'Billionaire learns honest work,' the tabloids will love it." Tony's smile was crooked, self-deprecating. "Besides, you can supervise. Make sure I don't create a monstrosity."

Stephen should have said no. He should have insisted on doing it alone, on not being weak, on not needing help. But his hands throbbed, and Tony looked at him with such open sincerity that refusal seemed impossible.

"All right," said Stephen. "But if you mess this up, I'll tell Mrs. Patterson it's all your fault."

"Acceptable terms."

 


 

Stephen had to admit that watching Tony Stark try to make a flower arrangement was unexpectedly amusing.

"Why so many thorns?" Tony asked, examining the stem of a rose with the intensity he probably reserved for weapons systems. "This seems excessive. Defensive overkill."

"Actually, they're called prickles," said Stephen, sitting on his workbench, coffee cup in hand. The warmth of the cup helped to ease the pain a little. "They're not thorns. Thorns are modified branches. These are growths of the epidermis."

Tony glanced at her. "You're enjoying this."

"Immensely."

"Great. I'm glad my suffering brings you joy." But Tony smiled as he said this, carefully removing the thorns from the stem, just as Stephen had taught him. "Then why does a flower need so many weapons, after all?"

"Protection. Roses are valuable—nutritious fruit, attractive petals. In nature, everything that is valuable needs to be defended."

"Hmm." Tony lifted the thornless stem, examining it critically. "A profound metaphor there, doc?"

"Perhaps."

They settled into a comfortable rhythm. Stephen directing, Tony executing with surprising care and attention to detail. His hands were steady, precise in a way that Stephen's no longer were. There should be envy in that observation, perhaps even bitterness. But, watching Tony's concentrated expression as he arranged the roses, the slight furrow between his brows, Stephen felt only something warm and complex.

"How is Peter?" Stephen asked as Tony added the gypsophila.

"Smart. Too smart. Starting to ask questions I don't have good answers to." Tony hesitated. "Yesterday he asked me why I don't drink at dinner parties. Out of the blue... 'Dad, why do you always drink water or soda when everyone else is drinking wine?'"

Stephen's chest tightened. They still hadn't talked about it—Tony's past with alcohol. They'd touched on the subject indirectly, with a few references here and there, but never a full conversation.

"What did you say to him?"

"The truth. More or less." Tony went back to work, avoiding Stephen's gaze. "I told him I used to drink too much and that I stopped because I wanted to be a better father. He asked if I stopped because of him. I said yes."

"That must have been difficult."

"Yeah, well..." Tony's voice went hoarse. "Six years of sobriety next month. You'd think it would get easier, right? The telling part. But every time I have to explain it to someone new, I feel... like I'm back there. Like I'm still that guy who couldn't get through Peter's parent-teacher meeting in second grade without a bottle of booze."

"You're not that guy anymore."

"How do you know?"

"Because this guy wouldn't be here at 9 a.m. on a Thursday, learning how to arrange roses so his boyfriend doesn't have to work while in pain."

Tony looked at it, something vulnerable crossing his face. "Boyfriend?"

"It's not... I thought we..." Stephen felt a heat rise up his neck. "What would you call it?"

"No, I... having a boyfriend is good. Having a boyfriend is great." Tony's smile was crooked, genuine. "I just didn't know if we were labeling ourselves yet. We've been kind of... undefined."

"I'm a scientist. I like definitions."

"Even if you sell flowers now?"

"Mainly because now I sell flowers. Everything else is uncertain. Labels help."

Tony set down the partially undone bouquet and walked over to where Stephen was sitting. He was careful as always, demonstrating his movements delicately, giving Stephen time to pull away. But Stephen let himself be carried away when Tony stroked his chin, his thumb brushing against his cheekbone.

"Boyfriend," Tony repeated softly. "I can handle that."

The kiss was soft, almost a brushing of lips. Tony tasted of coffee and something sweet he must have eaten earlier. When he pulled away, his gaze was serious.

"Sometimes I'll mess things up," Tony said. "The boyfriend thing. The thing about being there for you. I'm really good with technology and really bad with people."

"I'm not winning any awards in the relationship department either."

"Yeah, but you have an excuse. You're all tormented and melancholic about your tragic past and your chronic pain. Very romantic." Tony's tone was light, but his eyes scanned Stephen's face. "I, on the other hand, am just a recovering alcoholic with attachment issues and a smart kid who's terrified of failure."

Stephen held Tony's wrist, despite the dull ache in his fingers. "You won't let him down."

"You don't know that."

"Yes, I know. Because you're here. Because you stopped drinking. Because you notice when he asks questions and gives honest answers." Stephen paused. "Because you're already doing the hardest part: you're trying."

Tony's throat worked. "My father never tried. He just... existed. He told me I would never be good enough and then proved it by dying before I could change his mind."

"Then you're already better than him."

The words hung between them, laden with meaning. Tony's eyes shone too brightly, and Stephen felt a corresponding pain in his own chest.

"The flowers," Stephen said gently, giving them both an exit. "Mrs. Patterson."

"Right. Flowers. Romance for those who have been married longer than I've been alive." Tony cleared his throat, taking a step back. "How am I doing?"

Stephen examined the arrangement critically. In fact, it was very good—balanced, aesthetically pleasing, with the eucalyptus positioned just right to contrast with the roses.

"It wasn't so bad," he admitted.

"Enthusiastic praise from the expert."

"Don't let it go to your head."

Tony smiled, returning to work. "Too late. I'm already planning my new career. 'Tony Stark: Genius, Billionaire, Florist.' Sounds good."

"You'd go bankrupt in a week. You're spending fifty dollars on roses for a forty-dollar bouquet."

"See, that's why I need you. Business acumen."

His cell phone vibrated. It was a message from Peter: Can I go to the store after class? I want to show you my robotics project.

Stephen smiled, typing back with slow, careful movements: Of course. 

The immediate response: YES! Thank you! See you at 3:30 PM!

"Peter?" Tony asked, noticing the smile.

"Would you like to visit after class?"

Something tender crossed Tony's expression. "He talks about you all the time. 'Mr. Strange said this, Mr. Strange showed me that.' I'm starting to get jealous."

"Don't be ridiculous."

"I'm serious. Last week he asked if we could have a garden. A garden, Stephen. On a rooftop. Because 'Mr. Strange says that growing plants teaches patience.'" Tony shook his head, but he was smiling. "You get along well with him. Better than... well. Better than most people."

The praise settled somewhere deep in Stephen's chest, warm and terrifying. Because Peter was thirteen, and Stephen's sister was eight when she died, and sometimes, when Peter smiled or laughed, Stephen saw Donna's ghost in those smiles.

He pushed the thought away. Not now. Not today.

"The ribbon," said Stephen. "Red satin, in the third drawer on the left."

Tony found the flower and began the careful work of tying the bouquet. 

"Hey," Tony said softly, without taking his eyes off the tape. "Thank you."

"So that?"

"For letting me help. For not... for not excluding me when things get tough."

Stephen's throat tightened. "You're welcome."

 

The bouquet was ready.

"Beautiful," Stephen murmured.

Tony looked at him, not at the flowers. "Yes," he said softly. "That's right."

 


 

Mrs. Patterson arrived at 11:47 a.m., thirteen minutes before the scheduled time. She was a small lady, in her seventies, with gray hair and kind eyes, the type who always left generous tips and remembered to ask about Stephen's hands.

"Wow!", she exclaimed upon seeing the bouquet. "Stephen, this is exquisite."

"Actually," Stephen said, and he could feel Tony's eyes on him from where he was near the cash register, "Tony did this one. I supervised."

Mrs. Patterson's eyebrows rose. "The boyfriend?"

Stephen felt his face grow hot. "I... yes. The boyfriend."

"Well." She smiled radiantly at Tony. "Young man, you have a gift. These are absolutely perfect."

Tony seemed genuinely pleased, almost childlike in his delight. "Thank you, Mrs. Patterson. Stephen is an excellent teacher."

"I'm sure of it." She paid, added her usual generous tip, and stopped at the door. "You know, Harold and I have been married for forty-three years today. Want to know the secret?"

"What is that?" Tony asked.

"Let each other break sometimes. Let each other help with the breaking." She smiled at Stephen, a knowing look. "The rebuilding—that's where the love resides."

She left with the flowers, while the bells tinkled behind her.

Tony turned to Stephen. "She knows, doesn't she?"

"That I'm a disaster?"

"That we're both a disaster." Tony approached, cautious as always. "But she's right. About the help."

Stephen wanted to argue, to insist that he didn't need help, that he was fine. But his hands still ached, and Tony had made the roses look beautiful, and maybe—just maybe—being broken didn't mean being alone.

"Stay for lunch?" Stephen asked.

Tony's smile was answer enough.
