Summary:Remus couldn't do it; he needed his pack for the full moon. Harry could feel something coming and it was going to be big. Michael didn't understand; who were these two and why did they reek of the supernatural? Selene knew that there were other Lycans, but the older man didn't look like any she knew? HP/ Underworld crossover and slight AU! Slash!

Harry stared listlessly into the shadows surrounding him. There was a presence out there, waiting for him, stalking him. Harry's wolf animagus felt another wolf's presence, but that was where the similarities stopped. It felt bigger.

He'd been with Remus for several hours, awaiting the final phase of the older man's transformation. To say that Remus had been reluctant to endanger Harry would be a vast understatement. The werewolf completely balked at the idea of letting Harry even in the same fifty mile radius of him during his transformation, but the two of them had been together for every transformation during Harry's sixth year, so he could hardly stop it now.

The wolf in Remus had grown fond of Harry and was quickly recognizing him as a part of his pack and according to what the older man had mumbled when he had suddenly dropped in; the wolf had grown anxious, choosing to pace the confines of Remus' mind, constantly reminding Remus that he wouldn't be spending the next few days with his "pack".

At about midnight the previous night, Harry had been surprised out of his mind when a half werewolf, half human Lupin apparated into his room. They had barely made it five blocks to the small section of forest on the outer edge of Little Whinging. They had spent the night there and Harry had to take extra care to conceal them during the day because there was no way Harry could move Remus nor could he leave him.

It was only the second night and already they were running into complications. In his wolf form, Harry had chase off a couple of teenagers and their damn pit bull. The raven- haired man didn't know if they had seen Remus or not. As they ran away, Harry's keen ears had picked up the words; "…they come from?! Nothing… the cops… take care of…" Just in case, he and Remus had found a different patch of forest to hide in.

An especially painful howl attracted Harry's focus back to Remus. The man was on the ground withering in pain and as Harry edged his powerful black body closer to his friend, he felt that presence again, sliding over them like shadows. Harry could feel his fur bristle and stand up, the animal equivalent to goose bumps. Keen ears picked up the sharp snap of a twig, but the presence was closer, much closer.

Harry's hackles went up, his wolf yelling at him to fight, to protect the only member of his pack. With a swift whoosh Harry was back in his human skin, wand out and ready. Dark brows furrowed. At the sight of the wand, the dark, overbearing presence had receded.

Harry knelt down next to Remus and laid a comforting hand on Remus' back. Harry felt shivers trace his spine just before he heard the deep rattling breath behind him. Viridian eyes wide with surprise, Harry spun on his knees, only to see a raging werewolf unlike any he had ever seen.
