(written from a Production point of view)
Clara Bryant (born 7 February 1985; age 30) is an actress from Los Angeles, California who, in 1993, played the young Wadi Chandra in the Star Trek: Deep Space Nine episode "Move Along Home". Her costume from that episode was sold off on the It's A Wrap! sale and auction on eBay. 
Bryant made her episodic television debut in a 1991 episode of Gabriel's Fire, starring fellow Star Trek actress Madge Sinclair. Bryant's episode also guest-starred Gregory Itzin and David Opatoshu, with the latter playing her character's grandfather. (Phillip Glasser, who played young Ru'afo in Star Trek: Insurrection but whose scenes were ultimately deleted, played her brother.) She went on to have roles in a number of made-for-TV movies, including 1994's Once in a Lifetime (co-starring Fran Bennett and Duncan Regehr), 1997's Under Wraps (with Ed Lauter), and 2002's Due East (with Erich Anderson).
Ten years after her role on DS9, Bryant had a recurring role during Buffy the Vampire Slayer's final season as Molly, one of the potential Slayers. She most recently appeared in an episode of Numb3rs with Star Trek: Voyager actor Ethan Phillips.
