Alex chuckled lightly as he pulled his wand out of his bag and cleaned himself up, slipping his trouser up his cold legs. Amused by the fact she seemed embarrassed when she looked away. He left his shirt off because all of his clothes were damp, he just assumed that putting trousers on was common etiquette. He smiled and cleared up the clearing a little by putting the last of the bodies - rabbits and weasels into the ever rotting pile to one side. He moved around and faced the girl, his arms crossed over his thing chest.
"I'm covered in blood because I've just killed a few centaurs on my way here," he explained, having decided that it didn't matter what he told her, no one would believe her. He smiled and shook his head as he zipped up his bag; listening intently to make sure that the centaur hadn't followed him. He doubted they would. He bit his lip again and he looked down at her, his eyes narrowing slightly. "I answered your question...can you answer mine now?"
