Angel's loyalty to his friends comes back to haunt them in this chilling episode, an unsettling blend of the series' usual horrors with the more realistic issue of violence against women.
Angel and Cordelia both knew there would be consequences when he freed the partially demonic (but totally evil) Billy from a fiery prison in hell in order to save her. Those fears are realized when a wave of violence against women is traced back to Billy, whose mere touch has the power to bring out the worst in otherwise good men. The crew rushes to prevent another brutal attack, unaware that Wesley has already been infected---and he's alone in the hotel with Fred.
