Greg was still laughing, silently, internally, but Nick could tell. It was just that quirk of his lips, and Nick had to bite back a sign of irritation. "Got those DNA results for me, Greg?" he asked, determined to ignore the lab tech's smirking countenance.
"Yeah, sure, Nick," Greg said, and there was that humorous undercurrent in Greg's tone that set Nick's teeth on edge. "Sample one matched your vic, sample two was unknown. Possible perp, but..." Greg trailed off. "You said there was a lot of contamination at the scene."
"Yeah, there was," Nick said. "Could be meaningless, could be something. Won't know until we find out who did it." He turned to go. "Thanks Greggo."
Greg waved idly, already back to his microscopes, but Nick saw a flash of something under the lab coat that made him flush in embarrassed irritation. "Greg," he hissed. "Are you wearing it?"
Greg's lips pursed, trying to stifle the smile, but his shoulders began shaking and soon he was laughing full-out. "I'm sorry!" he gasped, looking up at Nick who had his arms folded tight across his chest and was glaring at Greg. "I'm sorry," he said again, insincerely. "But you should've seen your face!"
"I got three hours of sleep, Greg, and then I wake up bleary and didn't get any coffee before I opened the damn closet door."
"I can't help it if my Marilyn Manson T-shirt scared you, Nick!" Greg said, chuckling evilly.
Nick shook his head and walked out of the lab, his ears still red.
