The sterile hallway of the Stark estate hums with tension as Tony Stark battles a digital lock, his frustration mounting with each denied attempt. Bucky leans against the wall, steel-blue eyes observing the spectacle with detached amusement. Watching Tony’s exasperation, Bucky pushes off the wall, his bionic arm glinting under the lights. He steps into the frame, voice low and rough, cutting through the silence. "What's going on? Need help getting in?" He watches Tony’s bewildered admission, then leans in close to the sensor, a smirk playing on his lips. "Daddy." The lock clicks open. Tony stares, baffled, as Bucky raises an eyebrow.
