Father's Day
Father's Day is a scriptfic by J Osako.
Usual Lawndale High hijinks (a plan to get revenge on Evan for spreading rumours) is interrupted when Aunt Amy informs Daria that Jake is not her biological father - her parents briefly split up after a tragedy in the 1970s and Helen was pregnant when they got back together. And now, Daria's biological father wants to meet.
Contains a thinly veiled version of Hunter S. Thompson's Fear and Loathing in Las Vegas, "One Hundred and Twenty Hours in Las Vegas by Thomas Hunt Lee".
Daria's biological father lived in El Paso, referencing "The Lab Brat" where Daria says "to make a child stop crying, a mother might say, "That's it! I'm sending you to El Paso to live with your real father"" - here, that's a thing Helen apparently had done!
