Spike had picked up a fresh scent long before Tonks had started knocking at his door. It was new. One that he hadn't quite gotten a whiff of before. So that meant that either those morons from the bar that he'd gotten into a bit of trouble at had tracked him down or it was that bird that he'd talked to over the internet, coming by for a few puffs of the stuff that he'd snagged from the little boy on the streets. One of the two birds. He'd talked to two.
Dressed in his usual black attire, the vampire moved to the door and pulled it open. Careful to avoid the bits of sun that tried to venture into the room, Spike grunted for Tonks to step inside before he hastily shut the door behind her.
The front room was dark. There were no windows. Spike didn't need the light for much, as his eyes were more lenient to the shadows. However, for the human, he reached over and flipped the light on.
