After Buffy The Vampire Slayer ended in 2002, actress Sarah Hagan went on to work on other projects in film and television. The actress played a Potential Slayer named Amanda in season 7 of the hit supernatural drama series. She first appeared in season 7, episode 4, "Help", as member of a supposedly random group of students showing up at Buffy's guidance office.
It's eventually revealed that Amanda was sent to Buffy for beating up a student who is picking on her; a few episodes later in episode 12, "Potential", viewers learn that Amanda is actually a Potential Slayer. In fact, she ends up slaying a vampire who threatens her. Later, Amanda moves into the Summers' home, training to become a Slayer and becomes friends with the other Potentials who are staying in Buffy's home. In the series finale of Buffy The Vampire Slayer, "Chosen", Amanda is finally activated as a Slayer—along with all the other Potentials—and helps battle against an army of vampires. The last shot of Amanda sees her falling, apparently dead after a vampire snaps her neck.
Before actress Sarah Hagan became known for her brief role on Buffy, she was known for other projects. Her TV debut was in an episode of Ally McBeal, and her major break out came when she was cast as the character Millie Kentner on the cult show, Freaks and Geeks. After that show was cancelled, she appeared on Undeclared, and before she was cast in Buffy, she acted in the Jack Black movie Orange County and the show Boston Public.
After Buffy came to an end in 2002, Hagan appeared in episodes of other TV series. From 2004-2008, she held parts on Judging Amy, Grey's Anatomy, Medium, Close to Home, and My Gym Partner's a Monkey, the latter a voice role. From 2010-2013, Hagan appeared in episodes of Private Practice, 90210, Friend Me, and NCIS, and also had a recurring role on Breaking Fat.
Movie-wise, in 2009 Hagan appeared in the short film Someday We Will Get Married and the feature film Spring Breakdown. From 2010-2011, she was also in the short films Starter Home and The Bridge of Frank, and played Jess in a series of vignettes titled Jess + Moss. From 2012-2015, Hagan acted in The Most Fun I've Ever Had With My Pants On, Orenthal: The Musical, and Sun Choke. Despite Hagan's success in the television world since Buffy The Vampire Slayer ended, many fans of the show will always know her as Amanda the Slayer, a role where she managed to make a brief, but lasting impression.
