Steve started to give Tony hell, but Bucky interrupted.
"Why?"
"Why what?" Steve and Tony said together.
Bucky tapped the laptop.
Before Tony had a chance to say anything, Clint piped up.
"Tony's got a hard-on for new technology."
Pepper gave a startled laugh. She smothered it quickly, eyes dancing, when Tony gave her a indignant look.
"New to Tony," Clint amended. "He can't help it. He's always gotta try to figure shit out, how to make it better."
"And succeeding," Tony put in.
Bucky's eyes returned to the laptop. After a moment, he nodded. "Okay."
"Okay?" Tony looked confused.
