Debra to kill Dexter, saying she's a good person who's not like her brother. Dexter resigns himself to his fate and drops his knife. Debra, in tears, instead shoots a shocked LaGuerta in the chest, killing her. Difference from novel In the novels, LaGuerta's first name is "Migdia". In Darkly Dreaming Dexter, LaGuerta is portrayed as a spiteful, manipulative woman skilled only in political gamesmanship. In the TV series, however, she is cast in a more sympathetic light. In both the novel and the TV series, she flirts semi-openly with Dexter, much to his annoyance. In the first book, LaGuerta is stabbed to death by Dexter's brother Brian; in the TV series, LaGuerta remains alive and very much a factor in Dexter's life until her death at the end of Season 7.
