2. Happy Harrison
Yes, the happiest baby to ever giggle and babble on subscription television, Dexter Morgan's spawn, Harrison, is rarely ever shown upset, not a tear nor a tantrum, exhibiting constant laughter regardless of how grim the conversation or tense the situation. From a wee tot to a young lad, Harrison can always be counted on for a reassuring smile or a plot-furthering comment, never too upset his single parent and source of stability is constantly running out on him. How does this toddler remain so calm and eternally blissful despite being the offspring of a frantic and murderous killer always leaving his side? This brings us to the biggest leap of logic Dexter asks us to make.
