Ooh, here's a prompt: just about anybody telling Tony Stark, 'Now power down, sass robot.' 😀
Haha, that's probably what Pepper says to him before bed.

"Hey Tony, it's 4am. Time to come upstairs, baby."
Tony doesn't look up from his tablet, mumbling, "Can't just make up a new element, well I'll show him... Did it once, can do it again..."
"Come on," she soothes, sliding her fingers under his and pulling him away from his workstation.
He's almost in a trance as she guides him upstairs. He's still ranting incoherently about whoever challenged his engineering skills. She puts a toothbrush in his hand, helps him strip down to his boxers, gets him to chug a cup of water.
On the way to the bed, he's still talking. Does he ever stop talking?
"I can make a great robot. I am a robot. No, I'm more like a golem. Like, an iron golem. Do you think I should have called myself Iron Golem? It's not really iron, I just thought that sounded hardcore. Maybe I should be Titanium Alloy Robot..."
She's concerned about how late it is. "Are you free tomorrow?" Hopefully he doesn't have anything important to do tomorrow and can sleep as late as his body needs.
"No, I'm very expensive." He somehow winks sleepily at her. "You can't afford me. I know your salary."
"Okay, okay. Now power down, sass robot." She places a soft kiss on the tip of his nose and tucks the blankets around his chest. But it still isn't until she wraps herself around his back that he finally drifts off to sleep.
