Dexter Morgan doesn’t know how to love. He’s been upfront about that little fact, at least through his inner monologue, since audiences first met the forensic investigator and serial killer in 2006.

Dexter (Michael C. Hall) is a do-good vigilante killer who cleans up after the police by killing the criminals who fall through the cracks or evade arrest. But even he needs love, or rather, he learned over time that if he is to keep up appearances and conceal his Dark Passenger (aka his insatiable urge to kill), then he needs to be normal.
