Colette Mullen was the wife of the demon Cain. Colette knew what Cain was, but still loved him unconditionally, asking only that he give up his demonic ways and stop killing. Cain complied to her request, retired from the Knights of Hell and settled down with her. The other Knights did not take too kindly to this act and kidnapped Colette, leading Cain down a path of murder once again, and single-handedly killed all the Knights except for Abaddon, who had taken possession of Colette.
Abaddon attempted to use Colette to make Cain return to the Knights of Hell. When Cain refused Abaddon began to fatally injure Colette's body. Enraged, Cain drives the First Blade into Colette in an attempt to kill Abaddon, however he was too late as Abaddon was able to flee the body. As Colette laid dying, she makes Cain promise to not pursue Abaddon, and return to a life of peace. For which he complies.
In the present, Cain visits Colette's grave to tell her that he can no longer deny who and what he is and to look away after watching over him.
