What Do You Do? – The Proclaimers

Rick stood in the back of the hall, watching Horatio accept his promotion to Lieutenant. His fists were clenched so tightly that the muscles in his arms began to ache. All his loathing was focused on Horatio and Chief Burton. The promotion didn't bother Rick as much as the scandal did.

Seething, Rick remembered that late afternoon when he was looking for Horatio. Eventually he saw the redhead stumble out of the chief's office. His shirt wasn't buttoned properly, nor was it tucked in, and his tie was off. When their eyes met, Horatio's cheeks flushed madly and he quickly went out the nearest exit. Curious, Rick pushed open the chief's door.

Chief Burton stood at the file cabinets, turning in surprise. "May I help you, Sergeant Stetler?"

The chief's slacks were unzipped. Rick clenched his teeth behind closed lips and shook his head before leaving.

He transferred to IAB the next day, but decided not to expose them. It was for Horatio's sake…

Horatio's soft blue eyes met Rick's again. The redhead never could accept that he put his job before friendship, especially a friendship that he wanted to grow into something more.
