This works, as this scene (the entirety of it) shows Vincent’s true nature, and it takes place in a Nature Preserve.
From Protector of the Grey House:
Vincent waited patiently for the human to come closer. The man jogged along the path oblivious of any dangers. He wore headphones and looked to be lost in the motion of running. During the day, this path was well used by joggers, bicyclists, and walkers. As it was two in the morning, it was empty of people. The large vampire was surprised there was anyone. Lorraine informed him this path was only rarely used this early in the morning, and generally only by one or two people. Vincent kept himself hidden as he thought of his next steps.
They were in a Nature Preserve. Technically, the park was closed. Technically, neither he nor the man should be here. Lorraine looked for these types of things, to find humans they could use for sport, if it were needed. His sire assured him it was safe. The man lived nearby and snuck into the park every night after work. He was a supervisor at a nearby call center. If he went missing, there wouldn’t be a hunt. His death would not bring Slayers.
