Harry raised an eyebrow, eyes moving from Nell to the gentleman over the other side of the corridor, and then back to the brick-wall of a man in front of Nell. "I'm sure these gentlemen are very well aware that you're a boy, Nell, and that there aren't any girls here, so if their tastes run that way I can direct them to more suitable entertainments." He said, eyeing Brick Wall again, trying to spot any obvious signs of a weapon on him. "I hope that helps clear up any misunderstandings?"
He hoped it did. It hadn't been so long ago that a drunk, mistaking Nell for a girl, had set on him and left him bruised and bloody. Harry was going to do as much as possible to ensure he didn't have to dump another body in the river. Especially as, by the look of Brick Wall, he'd have to enlist someone else to help.
