After also draining Nick's cut-off arm of blood, Fergus began to clean up. He didn't care to clean up the blood stains, instead picking up Nick's corpse. He took off with his vamp speed and then dumped it into a hole he dug.
He'd been extra careful avoiding being seen during his walk in the pack with Nick earlier. Luckily for him, they'd taken secret routes, something Fergus was sure the late Cullen did as well. The last place people saw him with Nick was close to the bar, which was almost an hour ago.
Fergus had been reckless with this kill. He'd walked around with the victim before leading him to his house and killing him. But why? It was because he didn't care anymore. He didn't want to hide himself much anymore. Besides, he had a pretty alibi waiting for him back at the Gamma's house.
