Sunday night’s episode focused on the two new people in Dexter’s life, Harrison and Lumen, who are both vulnerable innocents, but for how long? Dexter, for the first time, is in the a position where he could groom an apprentice, either in his young or Lumen, who is eager to get revenge on her attackers, or in his own son.
As the episode opens, Dexter takes Harrison to a Mommy and Me class where he plays a parachute game with the other mothers, until the fun is interrupted by tears. One child scratched another on the face and Dexter assumes it was Harrison, finding it hard to believe he wasn’t effected by watching his mother die, the way Dexter was.
He examines Harrison’s fingernail for evidence but found nothing and asks the nanny if he is aggressive but she says no. Even though he fears Harrison will be like him, you can’t help but wonder if that’s what he secretly wants. While searching through the station’s databases for Lumen’s other attackers, he plops Harrison on his lap and tells him his plan to kill them before Lumen can, it seems he’s looking for a confidant.
