Her eyes had been focused on her feet, one part of her mind lost in thought, while she kept her ears split for anything, they usually didn't miss what was going on. She was approaching a corner to round when she heard feet on the sidewalk, nothing different. Probably just a person. It didn't sound like they were scrambling.
But when she did round the corner, she stopped dead in her tracks, eyes going wide. The aspirin she noticed, and he was dead, and this girl was...jumping over him? "What are you doing?" she half demanded, sounding horrified. Kara didn't necessarily think the woman had killed him, but the man was dead, and she was...playing with the body.
She positioned herself in a defensive stance, nothing serious, just braced. Someone was dead, this was the section for the Justice League to cover, and this womans position wasn't saying much for her.
