Before baby Harrison was even conceived on DEXTER, Dexter (Michael C. Hall) worried that any child of his might inherit his homicidal tendencies. It appears that Harrison, now ten months old, may have scratched the cheek of a playmate, drawing blood, which sends Dexter spiraling into anxiety. Not that he’s all that calm anyway, what with assault/kidnap victim Lumen (Julia Stiles) wanting Dexter to help her kill her remaining assailants, a desire that almost leads Dexter to mistakenly taking out the wrong man. Meanwhile, Quinn (Desmond Harrington) persists in his quest to tie Dexter to the mysterious Kyle Butler (the alias Dexter used to get close to the Trinity killer) and Batista (David Zayas) almost screws up a sting operation in his jealousy over what his wife/boss LaGuerta (Lauren Velez) may be doing to save her husband’s job. Deb (Jennifer Carpenter), continuing to investigate the Santa Muerte murders, finds clues in a very messy, maggot-infested murder scene.
