 was the head forensics coroner at the Royal Investigative Service. He served as the main antagonist in  The Beginning.

Appearance

Personality
Gilbert Ross was a very complicated character. At first, Gilbert appears to be a nice guy who harbored faith in Keith and wished for him to get over his sister, Erika's death. He also had a smoking problem which he tried to hide.

However, later in the series, it's revealed that Gilbert was actually not the man that he made himself out to be; having a 'dissociative personality disorder.'

For most of the time, Gilbert appeared to be normal to everyone around him, however at night, Gilbert's more psychotic side emerged to commit murders. In this state, Gilbert appeared to be rather ruthless and sadistic, often employing mind games against Keith and liked inflicting pain on others. However once the murder was over, Gilbert would reset himself back to his normal personality to forget the memory of having committed such murders.

Gilbert also suffered from a inferiority complex to Keith Flick. He constantly lamented that he was unable to beat 'Genie' and strived to beat him, even if that meant making Keith kill him.

Gilbert was also in love with Keith's sister, Erika. Despite being the one who killed her, Gilbert still talked to her being unable to get over her murder. He was also quite dependent on Erika's memory to suppress his more destructive urges.

Etymology
Gilbert is a Germanic name that means 'Bright Pledge.'

Trivia

 * It's interesting to note that the Germanic elements that make up the first part of Gilbert's name, gisil which means "pledge" also means "hostage," signifying that Gilbert is his own hostage to his more murderous instincts.
