On the upper level of the loft, Nick Knight keeps a sunbed. Dr. Natalie Lambert has instructed him to use it regularly in order to increase his tolerance for sunlight, to which vampires are allergic. Nick was seen using the sunbed at the beginning of "Killer Instinct". Later in the episode, after he had been framed for murder, his apartment was searched by several police officers under the supervision of detectives from Internal Affairs. His partner, Don Schanke, who was familiar with Nick's allergy, was confounded to learn that he kept a sunbed.
