Tony finds Steve and Bucky in the kitchen with the fridge wide open, talking quietly as they gesture towards it.

"What do you think you two are doing?"

Steve turns. "The light. There's a light inside of the fridge."

"And it knows when we're going to open it," Bucky looks confused as he closes the door, opens it, and huffs. "See?"

Tony snorts. "You're kidding, right?"

Steve and Bucky narrow their eyes. "Does it look like we're kidding?"

"Well.." Tony sighs, walks over to them, and closes the door. "The light doesn't know when you're going to open it. The light switches on the second the door is ajar."

"So it knows when the door is ajar," Bucky says quietly. "But it doesn't know when I'm going to open it..?"

Tony blinks. "Yes."

"Wow," Steve grins, patting Tony on the shoulder. "I guess you're not all that bad."

"Excus-"

"Anyway," Bucky grabs Steve's hand. "See you."

Steve waves as Bucky drags him away.
