A/N Headcanon 1.) If Vash is alone with one other person and they're a younger person, like Lily or Peter, he tends to open up and act like a fun fatherly figure, playing with them and whatnot. If there are others around, however, he hides that side of himself.

I do not own Hetalia, or the OC (Lassie Kirkland, she's 15). I only own the idea/headcanon.

Vash Zwingli smiled lightly at Lassie, taking her hand. "So. You get to spend the day with me. I'm sorry it's so last minute, but Arthur had work. So you're stuck with me."

Lassie nodded slightly, signing. 'I'm sorry I'm not talking…But I'm glad you were willing to be with me today.'

Vash shook his head, smiling more. "It's no trouble at all. Now. Where should we go?" He thought for a moment, then grinned and chuckled lightly. "How does ice cream sound?" He took her smile and nod as an approval, and led her gently by the hand towards the ice cream shop.

They sat in the ice cream store for a while, discussing various things. Vash talking, Lassie signing. It was a lovely time, but finally they had to leave. Vash stood, taking her hand and helping her up, then leading her out the door. Once they were outside, Lassie stopped him. He turned to her, a questioning look on his face.

"Th-thanks for today, Vash."

He flushed bright red and smiled, giving her a gentle hug. "Any time, Lassie."

Vash walked her back home, a stoic look appearing on his face when Arthur came out to meet them. "So, how was she? Not too much trouble, I hope."

Vash just shook his head the tiniest bit. "It was fine."He bowed slightly,

"Thanks again, Vash."

Vash smiled slightly when Arthur wasn't looking, one thought going through his mind as he walked away. 'It's no trouble at all.'
