Tony has no idea what time it is as he settles down on his chair in front of his main monitor, but he doesn't bother to turn to look at the little clock at the corner of his screen. For a moment he just sits there, listening to the silence and trying to ignore the way that his heart seems to keep pounding in his ears.
Hours ago - he really can't remember when - he had gotten into the suit and had flown away for a mission. Now he's home, all showered and changed, and maybe he should go upstairs to sleep for a few hours. It's well deserved, after all; he really can't remember when he had last slept, and for how long. He needs to be well rested to continue working on his plans for the expo. He needs to be well rested to go on another mission in case it comes up, and god knows that it does come up. He needs to be well rested in case Dylan comes over, because the last thing he wants to do is worry him.
Yet, even with all that in mind, he doesn't move from his spot. Not to get up, at least; instead he reaches for the keyboard and types in his password to continue working.
"Sir," Jarvis suddenly interrupts as Tony sits for a whole minute just trying to make himself remember what was the last thing he had been working on before flying away. "Perhaps some hours of sleep is for the best."
"We have work to do."
"Which cannot be done if you were to suddenly pass out from exhaustion. According to my observations--"
"I know what your observations say, Jarvis." Not really, he doesn't, but he has an idea. Frankly, Tony doesn't care. "We have work to do." Tony waits for Jarvis to say something else and insist, but silence follows and suddenly he doesn't know if he should be relieved or worried at what his AI is doing. Because, while he's good at keeping his secrets he's also good at divulging some of them in case he believes it's necessary. And, well, even if his orders had been to not utter a word of the special project they're working on, Tony hadn't programmed anything else just yet.
For a moment he considers getting up, going upstairs on his own accord, but he doesn't move. Because, if he did, well that just wouldn't be the way that Tony Stark operates. He likes to set his own rules. He says when things are done, and how. He's the one that likes to be in control of the situation, and he's the one that decides what he ends up doing.
Right now he just wants to work.
It has nothing to do with the fact that he's trying to ignore the rest of the world as he submerges himself in his work, really. Just how it has nothing to do with the fact that he's still not achieving that sense of indifference at the fact that Pepper went to see Bruce Wayne, and he's too irritated to really act normal. No, this isn't just one of Tony Stark's tantrums. Really.
Raking his fingers through his still wet hair from the shower, Tony stands but doesn't head towards the door. He just serves himself some scotch and plans to go get aspirin in a minute for the headache that keeps pounding against his temples. After that he'll set to work again, because he refuses to go to sleep yet no matter how exhausted he feels.
He's fine. Really. He's just fine.
