"ANGEL" RETROSPECTIVE: (5.15) "A Hole in the World”
Written and directed by Joss Whedon, the Season Five episode, (5.15) “A Hole in the World”, centered on the death of one of the series’ regulars, Winifred “Fred” Burkle. The slow road to her death began when a Wolfram and Hart employee named Knox accepts the delivery of a sarcophagus. When Fred touches one of the crystals that cover the lid, a puff of dusty air is released, making her cough. Later, she eventually starts coughing up blood before collapsing.
It turns out that by touching one of the sarcophagus’ crystals, Fred becomes infected by the spirit of an ancient demon named Illyria. The entire crew searches for a cure, but give up hope when Spike and Angel discover that the only way to save Fred's life would kill thousands of people. Wesley Wyndham-Pryce tries to comfort Fred as she dies and eventually witnesses the emergence of Illyria.
