Update 8
Abomination
Alek mindfraked Melody and stuffed the soul fragment of a little girl into her head, then strengthened the soul fragment (named Huggles) and tried to help it take over. Dr Al Beit managed to prevent this happening, but told Peter Raven (Melody's great uncle, by adoption) to find a recently dead body, preferably that of a little girl.
Raven raced out into the blizzard and didn't find any convenient little girls wandering around for him to kill, but he did see Deryni Ironwood, a middle aged woman who is drawn to people on their deathbeds. A little boy who had lost some toes to frostbite was now dying of gangrene. Raven could have healed the child, but instead waited until he died, snatched the body, and took it back to GLoG. Deryni followed.
At GLoG, Dr Beit forced the Huggles soul into the boy's body, which brought it back to life. When Deryni arrived, she was at first horrified to see the child alive again. When she touched the child and felt that it was inhabited by another spirit, she was utterly sickened and called it an abomination. The child cried that it wanted to go home, so Deryni took out her mining pick and killed it with a blow to the skull. Alek then shoved the Huggles soul into Deryni, while Turtle hauled Deryni off to the detention wing.
The next day, Pris, a Lawful Good celestial, exorcised the Huggles soul from Deryni. Huggles went on to the afterlife, and Deryni is still imprisoned.
