Plot hole: Throughout the series, Sandy always refers to Daria as "Quinn's cousin" or "that girl that lives with Quinn" or other random titles for Daria (not knowing that Daria is Quinn's sister). Although Quinn admits to Sandy that Daria is really her sister in one of the last episodes of the final season, in this first episode of the series, Sandy is in the crowd watching Daria give a speech and Daria reveals to everyone Quinn is her sister (embarrassing Quinn). Sandy should already know they're sisters.
Daria (1997)
1 plot hole in Season 1 generally - chronological order
Starring: John Lynn, Julian Rebolledo, Tracy Grandstaff, Wendy Hoopes
Continuity mistake: Daria arrives at school without her glasses (her choice). When the scene changes to Mr. O'Neil's class, first shown from the back facing O'Neil and the backside of students, Daria (sitting on the left of the screen) is shown from behind and her glasses are showing on her face (as usual). When Daria is next shown talking close up in the remainder of the scene, she is without her glasses again.
Trivia: Wendy Hoopes did the voices of Jane, Helen, and Quinn. This explains why sometimes when Helen is talking in an excited tone and her voice goes higher, she sounds exactly like Quinn.
Question: Whenever Kevin talks to Mack, Kevin calls him "Mack Daddy." Mack always responds with "Don't call me that." What is the reason Mack doesn't like to be called "Mack Daddy"?
Answer: "Mack Daddy" was a 90s phrase meaning "Ladies man," and Mack simply doesn't like the stupid nickname.
