Tonight in HD: January 3

SoHo Highlight: Dexter (Sky 10, 8.30, 5.1) Dexter uses lessons he learned from Brother Sam to explore new leads in the Doomsday investigation while Debra butts heads with Captain LaGuerta over the case of a dead call girl. Most US blogs noted Sin of Omission continued Dexter’s disappointing deterioration this season, with arguably the best reason for watching this episode being the changing dynamics in the Dexter-Debra relationship. “If there’s one thing Dexter fans have been waiting for, it’s Deb learning Dexter’s biggest secret,” Cinema Blend said. “We all know that sooner or later, it has to happen. As Deb is the closest person to Dexter, seeing her reaction to understanding the truth about her brother is sure to be a huge moment for the series, if/when it happens. Deb and Dexter’s relationship has always been a lot more one-sided than Deb realises, but based on tonight’s episode, it looks like that could be changing.” ✭✭✭
