Flack leaned back in his chair, staring at Stella. She sat hunched over her desk, her dark curls hiding her face as she once again went over the evidence that they had. Don knew that he was supposed to be doing the same, but sitting right next to her was proving too big of a distraction. He let his eyes focus on her hair, on the tight curls and the streaks of lighter brown he knew to be natural. Once again, his fingers itched to touch it, to know what it felt like to run his hands through it from root to tip. Finally, he couldn't resist it any longer. Reaching out, he took a hold of one of the curls, rubbing it gently.

"You should let your hair grow out again," he said quietly.

She turned to look at him, startled by the sudden contact. "What?"

"Your hair," he repeated. "I liked it long."

A smile crept onto her face as she turned back to her work. "Did you?"

Flack watched her carefully, seeing the pink tinge that slowly made its way up her neck and onto her cheeks. Chuckling, he tucked her hair behind her ear, his heart rate speeding up when he felt her shiver as his fingers brushed against her neck.

"You're blushing," he murmured.

She didn't meet his eyes, but the smile stayed on her face. "I am not."

"You are."

Looking up, she stared at him for a moment, the blush all over her face now. "Yeah, well, you're flirting."

"I know."

The answer left Stella flabbergasted. She opened her mouth to say something back, but words eluded her until she just sighed and pointed to the files on the desk.

"We have a case to work on."

As they both turned back to their work, Don stole another glance. Stella may have effectively ended the conversation, but she was still blushing - and still wearing a grin.
