Steve looked up from his sketchpad to check the time, 3 am. He closed his sketch pad and reached up from his spot on the floor and put it on top of the end table beside him.
"Jarvis? Is Tony still awake?" he asked the A.I. as he got up.
"Sir is currently resting his eyes," Jarvis said fondly, well as fondly as an A.I. was able to.
Once Steve put his art supplies in the end table he walked out of the room. He meandered down to Tony's lab. Asking Jarvis to unlock the door for him as he quietly walked in. The solider couldn't stop the small chuckle that slipped through his lips at the sight before him. The genius had he head resting in the crook of his elbow with his other arm across the table, wrench in hand. In front of him happened to be whatever project he had needed said wrench for.
Dummy, who was hovering next to Tony, looked up when Steve had entered his creator's lab. Before Dummy was able to make a hummy greeting to him, Steve put a finger to his lips. Slowly he made his was around all the mislaid, most likely tossed away, parts that were scatter on the floor to get to the sleeping man. Once he made it over to Tony, Dummy started backing away, beginning to clean up his inventors mess on the floor. Steve slowly picked Tony up bridal style, before making his way back upstairs to the bedrooms.
In the middle of the second set of stairs Tony mumbled something along the lines of 'not tired' before he nuzzled into Steve's neck, relaxing his grip on the wrench.
"Of course not," Steve mumbled as he reached the top of the stairs. He moved Tony slightly to open the genius' door and shook his head at the sight of the genius' large, rarely slept in bed.
"Why you insist on having such a huge bed I will never figure out," Steve mumbled as he moved the blankets down the bed, before he set Tony down on it gently. Only after he got the billionaire's shoes off did he tuck him into bed, then he, himself finally went to bed, knowing that everyone in the tower was where they were supposed to be.
If Tony ever wondered how he managed to find himself in bed, shoe less, and cuddled up with his wrench, he never said anything.
