I said 'just one' but then I thought of another story, and then another... Unfortunately, my English isn't very strong, so each story's a struggle.
Anyway, here's one set a few months after IM2. (It's not necessarily a follow-up to Just one, by the way).
Just a little bit of news
JARVIS tells Tony more than he's prepared to hear.
Tony Stark entered his workshop and made a beeline to the kitchen, enticed by the aroma of freshly brewed coffee.
For once, Dummy had managed the task without causing a short circuit.
"Well done, Dummy," Tony said gruffly. "Maybe I won't be sending you to that city college, after all." Looking over his shoulder, he said, "JARVIS? You up?"
"Yes, Sir."
"Any news?"
"I have finished your monthly medical check-up, Sir."
"Great," Tony said. He was keeping close tabs on his health these days. After his Palladium scare a few months before, he wasn't taking any chances, so he'd created a medical system that allowed JARVIS to run an unobtrusive medical check-up at any given time.
"Shall I render the results?"
"Thrill me." Actually, he was only vaguely interested; he knew JARVIS would have alerted him the moment he'd detected anything unusual.
Right now, he was more interested on the rich flavor of his Expresso. He took a sip, held it in his mouth for a moment, then slowly let it slip down his throat...
It was heavenly.
"- in conclusion," JARVIS said at last, "An increase of green vegetables consumption is recommended, sir."
"Yuck," Tony muttered. Ah, well. At least JARVIS hadn't mentioned anything about his increasing coffee consumption -
"Sir," JARVIS continued, "I have the results of Ms Potts' medical check-up too."
"You ran a check-up on Pepper? Why?"
"Since her status as a visitor has changed from that of 'employee' to girlfriend-"
"I prefer to call it 'visitor with privileges'," Tony interjected, but JARVIS ignored him.
"- I considered it appropriate to run a medical check-up on her too."
"Well," Tony said, raising the cup again, "I hope she's as healthy as she looks."
"She certainly is," JARVIS said promptly. "Her pregnancy is developing quite normally indeed."
"Wha -" Tony spoke (or tried to) while still holding a mouthful of coffee –not a good idea at all. He coughed and spat coffee all over the floor, while fending off Dummy's clumsy attempts to help at the same time.
"Oh, shit," he managed at last, "JARVIS, please, tell me I didn't hear what I think you just said!"
"There is nothing wrong with your hearing, sir," JARVIS said inexorably. "You must have heard me correctly."
Gee, JARVIS needs to learn how to deliver these news!
