The Buffy episode Fool For Love and the Angel episode ‘Darla’ aired in the same week in US. Both shows covered the 1880 turning of William to Spike, and how it affected Angelus.
In the Buffy episode, William is seen walking down the street with his poetry pages, where he bumps into some passerbys on the street. Those people are Angelus, Darla and Drusilla. William then continues down the alley where he is approached by Dru, and is sired.
In the Angel episode, we see the same scene in the street only from the perspective of Darla, Angelus and Dru. William bumps into them says, “Watch where you’re going!” Dru then sees William for the first time, and follows Angelus’ advice to “make herself a playmate”.
