Angel: Billy (2001)

As he gives her lessons in swordplay so she can better defend herself in future battles, Angel (David Boreanaz) is surprised to learn that Cordelia (Charisma Carpenter) is a quick study; she credits her years as a Sunnydale cheerleader. It's Fred (Amy Acker), however, who really needs to defend herself when a half-demon with the power to turn men into misogynist murderers turns Wesley (Alexis Denisof) into a clone of Jack Nicholson's character from The Shining. William "Billy" Blim (Justin Shilton) is the privileged nephew of a congressman. He's also the fiend Angel was forced to free from a hell dimension by Wolfram & Hart (see "That Vision Thing"). His very touch brings out the hidden woman-hater in every man, and Angel proves incapable of stopping the spread of his infectious magic. As a transformed Wesley stalks the resourceful Fred through the Hyperion Hotel, Cordy attempts to kill Billy. Angel stops her and Billy touches Angel, but the vampire hero proves impervious to the half-demon's magic. Combat erupts, but it's Lilah Morgan (Stephanie Romanov) -- who suffered a savage beating at the hands of the Billy-infected Gavin Park (Daniel Dae Kim) -- who ultimately defeats her own client. Later, Wesley grapples with the terror he inflicted on Fred and begs her forgiveness. Originally broadcast October 29, 2001, on the WB network, Angel: Billy marked season three, episode six of the supernatural comedy drama. The secret crush on Fred that Wesley nurses in this episode will have major plot repercussions throughout the second half of season three. ~ Brian J. Dillard, Rovi
