As the series dropped to number four, it continued to be known for violent storylines, often focused on organized crime. 2004 marked the beginning of the series' month-long sweeps storylines. That February, the Port Charles Hotel Fire story saw the cast trapped in the burning hotel, including a location shoot involving a helicopter. During the ordeal, Edward suffers a heart attack, Courtney rescues a lady who later rewards her with large sums of money, and Scott Baldwin is presumed dead. That summer, while the 2004 Summer Olympics were screening on rival channel NBC, the show launched another major storyline that involved a masked serial killer terrorizing the Quartermaine mansion for five episodes. The storyline was seen as an attempt to lure NBC soap opera viewers, especially due to the similarities to the recent serial killer storyline that had taken place on rival NBC soap "Days of Our Lives". In "General Hospital"'s version, the killer is revealed to be Mary Bishop, attempting to kill Emily Quartermaine but killing Sage Alcazar instead. Mary is the widow of Nikolas's doppelgänger Connor, who tries to convinces Nikolas that he is actually her husband while he's experiencing amnesia. Emily tries to make him see the truth, causing Mary's rampage. The confrontation ends with Nikolas shooting Mary, who later dies in the hospital when her medications are switched by Lorenzo Alcazar, seeking revenge for the death of his niece Sage. The year ends with the wedding of Emily and Nikolas.
