Erin the Head was written by Kara Wild in January 2000 and is the thirtheenth installment of the Driven Wild Universe. Like most other installments, it is written in quasi-script form with three Acts and commercials.
Daria's cousin Erin leaves her husband and stays with the Morgendorffers, under the guise of wanting to learn more about "successful" marriages from Jake and Helen. However, Daria soon discovers her true reason for coming: Erin wants to get together with Trent, whom she met briefly in None in the Family, Part Two. To her own surprise, Daria agrees to help her.
