Trevor

 was a new vampire and prisoner at the Safe Zone under the Supernatural Crisis Act in 2009.

Biography
Trevor often attempted to fly into its force field when blood rations were distributed, desperate that is was never enough. After one of these attempts, Spike advised him to stop hurting himself, since he'd need even more blood to mend his bones. Trevor suggested that they should take the Slayer together and feed from her; in response, Spike sent him to the end of the line.
