"Mulder! Have you lost your marbles?" Scully retorted, eying her partner sceptically.

He grinned back and shook his head, reaching into his pocket as if checking for something. "Nope, they're all here," he replied teasingly. "Lucky, huh? We'd have had to go back to the mountains if they'd gone missing!"

His eyes lit up with a mischievous twinkle and he moved closer to Scully as she attempted and failed miserably to hide a smile.

"Yes, Mulder," Scully replied, sarcastically. "It's very lucky."

"It certainly is, Scully!" Mulder quipped lightly, brushing his hand against hers.

Scully smiled resignedly. "Sure. Fine. Whatever."
