Gwenog had been out for an early dinner at Bella's and had decided to walk to the end of Diagon Alley before she apparated home. At the sound of an Apparition crack from the alleyway she was approaching she frowned. It wasn't unknown for someone to use alleyways for disapparating, but usually they didn't bother to more than step just inside and that had sounded like it was some way down the alley. Curious, she glanced in as she passed.
It hadn't registered at first, but a couple of steps later she stopped, realising what she had seen. She did an immediate about-face and thundered into the alleyway, wand-drawn. Quidditch was a pretty violent game so she was accustomed to blood, but the people involved knew about the possibility when they got into it. The alleyway wasn't well lit, but it looked decidedly bloody and violent.
"Shit!" she said loudly, scanning the alleyway for anyone else who might have hurt the huddled figure against the drainpipe. "Fuck. Okay, they've gone," she said, finally crouching down to discover the figure was a thin man, battered and bleeding, and bare from the waist down. That brought a curl of rage to her belly and she growled slightly in her throat.
