Z didn't move as Sparrow approached her; rather, her cocky smile grew more smug. But then Tim stepped between him, stopping the shorter woman in her tracks. 
Ace rolled his eyes to the back of his head for a moment, a gesture of annoyance, then looked at Z. "Can you give me a minute, please?" He asked her. Z smiled sweetly at him as she nodded. She patted his ginger hair before walking to the nearest ice cream shop. Ace redirected his attention to Sparrow.
"Look. I only get to see her once a year, so just avoid her for a couple of days," Ace stated rather blandly. "Then you won't have to see her again." He certainly wasn't going to send Z away, he hopelessly in love with her and would prefer not letting her stay during the only time she wasn't busy.
