Seth

Seth was a Manticore escapee. He was never mentioned or seen within the series, he was only seen in the Dark Angel novels.

Post-Escape
Seth had been working as an Eyes Only operative and just days before the start of the series. Logan using his new found X5's skillset to further his never ending thirst for truth, which leads to one of the darkest secrets of shame between Logan and Max. This secret was not exposed in the television series but only in the spin off novels afterwards Dark Angel: After the Dark. Max and Seth do finally meet up briefly in Dark Angel: Before the Dawn at the end of the novel only briefly resulting in Seth being wounded in a deal gone bad and plugging to his death from the Space Needle's Tower in order to escape from Manticore officials closing in; in addition, helping to save Max by allowing her the opportunity to escape. The setting was atop the Space Needle where Max later in the television series always purched to look over the city and find peacefulness; however, the novel exposes this to be the place she goes to be with the only X5 she had contact with since her escape from Manticore and to continue to be with his spirit, in loving memory of her lost brother. This in turn fuels Max's desire to be reunited with her family!
