A/N. I got this idea from the Charmed episode when Phoebe changes into a mermaid. Hope you enjoy.

Harry sat in his potion's lessons. Snape was going on about some sea creature potion. But Harry wasn't listening. He'd been depressed since he'd come back to school, 2 months ago. Harry had just started 7th year, and should've been worrying about NEWTS or the Quidditch match. But niether of those things had crossed the young wizards mind. No his thoughts were directly on a certain blonde haired Slytherin, less the 2 feet away from him. Harry had always had a suspision he'd liked men over women, and had realised he was gay back in 4th year. Alot of the school knew his prefrece, but they didn't mind. He remebered how he fell for Cedric, but that had ended terrible for him. Yet he'd slowly got over Cedric's death, and his affection went onto one Draco Malfoy. Harry had realised that he liked Draco back in 6th year. Unfortunately over the summer Harry had realised that their was no way Draco could love him. Draco hated him, despite his father having worked along side Snape as a spy. Plus Harry was pretty sure Draco was straight. So since he'd returned to Hogwarts his heart was empty and cold.
'Potter pay attention!' shoute Snape, bringing Harry out of his thoughts.
'Sorry sir.' mumbled Harry.
Draco watched Snape shout at Harry, to pay attention. He expected the black haired boy to retort, and insult the Potion's master, like normal, but he was shocked to see Harry mumble sorry. Harry hadn't even put any hatred in his tone, like he used too. Draco knew that the Boy-Who-Lived had been acting differently since returning to school. He had thought that he was worrying about NEWTS, but the boy hadn't been paying any attention in any of his lessons. Draco had became fond of the black haired boy, back when they first met. Draco always knew he was gay. He'd been heart broken when Harry had refused his friendship. For the past 6 years Draco had constantly fought with him, hoping he'd get over the crush. Yet his love never disappeared, and once his father become a spy he just gave up the fight. He had helped killng death eaters in the Final Battle, last year, to prove to everyone he wasn't evil. Since Voldermorts death, he had bee trying to get Harry's attention. Yet the 17 year old boy wasn't paying any attention anymore. Droaco had asked aroud to find out what was wrong, but had got no one knew. A few people had already guessed that he loved Harry, but it was kept secret until Draco had told Harry. He saw people begin to move. They had to make a sea creature potion. The potion would turn a person into the creature that matched his heart. Snape had said that they were not to test it, as there was no spell or potion to turn back. Only the person affected could change themselves back. Draco had been paired with Blaise, and the two began to make their potion.
Harry had been paired with Neveille. Not that he really cared. He was already failing all his classes, and had been to see Dumbledore more times than he could remember. His friends, godfather and Remus had asked him what was wrong. But he didn't answer. He just walked around feeling complettely alone. Harry was so busy caught up in his own thoughts that he didn't see Nevielle knock the potion. The first indication he got that something had happened, was when he felt himself change into something.
