Story Summary (Y/n) has always known Tony Stark is her father; they agreed to keep it a strict secret to protect her from enemies like Hydra. She joins Stark Industries as his intern, acting like a stranger to him in public. A lab accident grants her molecular powers, drawing Hydra to attack. After fending them off together, the secret holds—until one small slip-up gives her away to the Avengers. The Slip-Up The team walks in post-fight. Tony’s checking her hands, distracted, and says: “C’mon kid, let’s get you patched up—your mom would kill me if I let you get hurt worse.” (Y/n) rolls her eyes, automatic: “Dad, I can fix my own cuts, remember?” Silence hits the room. Steve blinks, Nat smirks, and Thor booms: “STARK! YOU HID A DAUGHTER?!” Tony just groans; (y/n) goes bright red. The secret’s out.
