There is no happy ending for a serial killer — at least according to “Dexter.”
Dexter (Michael C. Hall) decided to settle down with Hannah (Yvonne Strahovski) and his son Harrison instead of ridding the world of the Brain Surgeon Saxon (Darri Ingolfsson), but in exchange, he lost the one person who he could ever truly love, his sister Debra (Jennifer Carpenter). Forced to be the big brother and protect her, Dexter pulled the plug on his foul-mouthed sibling after learning that she’d never be able to take care of herself when she suffered a major stroke — essentially making her Dexter’s final kill.
