Draco sat in his dimly lit room still fuming from his earlier encounter with Harry. "How dear he do that to me" he thought with an inflated ego. As his room got darker so did his thoughts, as he plotted his revenge on Harry.
It was early in the morning as Harry climbed out of his tent and into headed toward the bathroom to take a shower. He had gotten in the habit of getting up really early to take a shower since he realized the guys in Slithering all wake up at the same time and hog the shower for at least an hour. He was sure that no one would be up so early, but unknown to him Draco was quietly peering at him from a peep-hole he had made using a spell from the library. Harry rubbed his eyes lazily as he stripped off his clothes and hopped into the shower. He let the hot water run over his body as he began to lather up his washcloth. Just then Draco ripped down the shower curtain, snapped a picture of him, and sprinted out the door. Harry grabbed his towel and wrapped it around him and chased after him. "This is going on my wall" Draco yelled over his shoulder as he pulled out his wand and disappeared into a cloud of smoke. Harry stopped in his tracks and pondered Draco and his intention. "Malfoy isn't gay so I doubt he'll do anything with that picture" he thought as he shrugged and headed back to the bathroom to finish his shower.
When Harry got back to his tent at the end of the day, he found an 8 x 3ft poster of him naked and dripping wet hanging on the wall next to Draco's door. Harry's face was bright red from embarrassment, as he tried frantically to rip down the poster, without luck. After 10 minutes of trying, Harry returned scurried off, both deeply disturbed and mortifyingly embarrassed.
