Complete story — includes the ending
In the aftermath of last season's finale, Rita's death has left Dexter feeling responsible and guilty for not being there to save her from the Trinity Killer. Unable to deal with the trauma, Dexter makes a drastic decision that will affect everyone around him. Quinn stirs up trouble at the station when he notes that Rita's murder, which is being pinned on the Trinity Killer, does not fit his normal murder profile. Things get even more heated when Quinn learns about Dexter punching the neighbor over him kissing Rita, and suggests to LaGuerta that they consider the possibility that Dexter is the murderer. Meanwhile, Quinn offers Debra support, causing her to see Quinn in a new light.
