TV Guide Description for Episode Six - 'All The Way'.

All the Way
60 min.
In a quirky and erudite episode, a sudden announcement sends the Scooby Gang into celebration mode on Halloween, but plenty of frights come to light when Dawn disappears.
Anya (Emma Caulfield), who has been bugging Xander (Nicholas Brendon) to announce their engagement for months, finally gets her wish. After Xander drops his bombshell, Buffy and company throw a party for the couple. Only then do they realize that Dawn (Michelle Trachtenberg) has sneaked out with a friend (General Hospital's Amber Tamblyn). Out on the town, the younger Summers winds up meeting a teen (Kavan Reece) who craves more than just mischief. Zack: Dave Power.
