Synopsis by Brian J. Dillard
Cordelia (Charisma Carpenter) experiences yet another vision, this one involving danger to a young family. Angel (David Boreanaz) rushes to the scene and barely saves a sleepwalking boy named Ryan (Jesse James) from getting run over. Wesley (Alexis Denisof) realizes that an Ethros demon (Anthony Cistaro) has possessed a member of the boy's family -- mother Paige (Katy Boyer), father Seth (Will Kempe), or daughter Stephanie (Ashley Edner). With the help of some magic brownies, the team roots out the demon, who is hiding inside little Ryan himself. With no priest available, Angel himself must undertake the exorcism. But when the magic box procured by Cordelia to contain the expelled demon proves insufficient, Wes and Angel must hunt the thing down and kill it. Its dying pronouncement is that it had been trying to escape Ryan's body all along -- because the boy himself was pure evil, more monstrous than any demon. Angel and Wes rush back to the family's home just in time to save little Stephanie from Ryan's pyromania. Originally broadcast February 15, 2000, on the WB network, "I've Got You Under My Skin" marked season one, episode 14 of the supernatural comedy drama.
