"Hey Tony, Jarvis said you wanted to talk to me?" Katherine said as she walked into the lab. Tony was looking in a mirror before he turned to her, waving her over.

"Yeah, come here and answer this question." He said. She raised an eyebrow but walked over to the man.

"What…"

"Can you see all my gray hairs!?" Tony asked quickly and loudly. The woman jumped slightly.

"What?" She asked, blinking once.

"My hair! Can you see gray?!" He asked again, coming closer to the woman, allowing her to see his hair. She looked at it before looking at his face, he was 100% serious.

"Um… yeah…" She said, unsure of what she was supposed to say at that point. Tony groaned as he walked away from her, deeper into the lab. She woman's brow furrowed in confusion. She looked up at the roof. "Jarvis, help."

"It would seem that Mr. Stark is worried about growing older." The voice said.

"Seriously Tony? That's what you're worried about?" She asked. She jumped in surprise when Tony came over to her from a completely different direction.

"Yes. Have you looked at Thor? Natasha? Pietro? Wanda? Steve? You?" Tony asked, his arms flailing.

"Okay, first of all…" She thought about what she was going to say. "We are all younger. But Bruce is gray as well and Logan is graying as well. You're not old."

"You just said that Logan was graying! He's almost as old as you!" He said, pointing to her. She bit her lip. That didn't work out as planned.

"Okay… how about this? If you're so worried about it, I'll help you dye your hair." She said, trying to defuse the glare she was getting.

"Seriously?" Tony asked, his gaze softening.

"Yeah, just pick out the color you want and we'll do it." She said, smiling at him.

"Okay." He said, turning to look back in the mirror. Katherine rolled her eyes.

"Come on, let's go get some lunch." She said, nudging Tony's shoulder as she made her way out of the lab.

"What did Tony want?" Steve asked after everyone had cleared out the kitchen.

"He's getting gray hairs. He's worried about getting old." She said, smiling at the man as she cleaned the kitchen. She had been the one to cook and that usually meant that she was the one to clean the kitchen as well.

"Why is he worried about that?" Steve asked and the woman shrugged.

"It's Tony; do you really want to know?" She asked and the man shook his head. She chuckled as she continued to wash the dishes.
