Dorian Gray

 was in a memory accessed by Bernice Summerfield, Ruth and Jack, an expert on psychosis. He had a long experience on these matters, and wasn't a doctor. He encountered a patient Caitlin who made Amelia Blythe kill herself. Dorian told Dr Warlalo and Dr Hawke that Caitlin was the imaginary friend of Blythe's. In another memory, he later became interested in a painting that changed over time. He wanted it, to stop people's souls from being absorbed in it. In another memory, he was in a relationship with a man called Spencer Price, and he found him interesting. He later attacked Spencer in one of Spencer's dreams. He paid Benny, Ruth and Jack to find his portrait, whilst he lived his portrait died. (AUDIO: Shades of Gray)
