Angel does not speak aloud during this episode, only in voiceover. This is the only episode of the series in which he does not have any dialogue.
Multiple shots from this episode were used in the opening credits for seasons 3, 4 and 5, including at least two shots of Angel and one of Lorne.
Living up to its title, this episode resets all the characters. Joss Whedon did some major rewrites to Mere Smith's screenplay to accommodate these changes. Smith was very happy with the amendments.
Wesley tells Angel that "someone has to fight the good fight," ironically echoing a sentiment that Angel himself taught Doyle.
This is the first episode in the Buffyverse where we hear Drusilla call Darla by name. It's one of only two episodes where she does so, the second being Destiny (2003).
