|~ Ryan Anderson wanting to kill his sister for having more marshmallows in her hot chocolate then he does in his|
Ryan Anderson is the true antagonist of the Angel episode "I've Got You Under My Skin", though his evil nature is not revealed until near the end of the episode - although a one-shot villain he was fairly unique amongst the Angel villains in that not only was he human (at least in appearance) but he was also a child.
Ryan Anderson was a young boy who was "possessed" by a demon. His parents called on Angel Investigations to aid their son and they did so - during this exorcism the group were convinced that Ryan was an innocent child under threat from a malevolent force and fought to get rid of the evil within him.
However when the group finally tracked down the demon they felt responsible for the possession they found out the disturbing truth, the demon had actually been the prisoner - and was actually glad to be free from Ryan, whom it claimed was a soulless monster even by demon standards.
Back at Ryan's home the demon's words are proven true when the boy complains to his parents that his younger sister has more marshmallows in her cocoa than he does, when they think nothing of it he decides to exact his own justice - namely locking his parents in their room while setting his sister's room on fire, standing in the hall to watch as the terrified girl awoke to a room full of flames.
Ryan's attempt at murder failed however when Angel literally smashed into the girl's room (via a window) and rescued her from the flames, along with the rest of the family - including Ryan (who showed no emotion over what he had done).
In the aftermath of the event Ryan is seen being taken away by Social Services for evaluation - his father thanks Angel for saving his family and asks if their is anything that can be done for Ryan, Angel unfortunately can't answer the question and the episode ends.
