When 7th Heaven (once again) wraps up its storied run, the May 13 series finale will tie things in a neat little bow, yet also offer hope for the future. As Haylie Duff tells TVGuide.com, "There is a lot of resolution, and a lot of new beginnings, as well." Though she was only with the Aaron Spelling creation for two of its 11 years, Duff - who stars in the April 7 Lifetime movie Nightmare - says it was an honor to be a part of "a show that will go down in history," noting, "Everyone's experience was so wonderful and we took away from it everything we wanted to, which I think is special and important." - Additional reporting by Megan Cherkezian
