Angry now, unsure of why she was following him, Jennifer ran up behind the guy and stood next to him on the corner. The other cops were watching her every move, unsure of what she was doing, or why. Or why she'd left the crime scene.
"Excuse me." She said, sternly, impolitely. "If there are two serial killers in this murder case, then that means that there are four."
Jennifer held up her hand with four fingers extended.
"Two for this one. Two for an entirely different case that you seem incapable of grasping. Who the fuck are you, anyway? WHY am I talking to you? Why do you make me so goddamned angry?!"
If she'd been one for punching people randomly, she might have done it. But she was still a cop at heart and an upstanding citizen. And a nice person, really.
