The Ice Truck Killer strikes again, leaving a real nightmare before Christmas at Santa's Cottage. Sergeant Doakes becomes more suspicious about Dexter after his ambivalence about Batista's survival. Dexter finally finds he is connected to the Ice Truck Killer over a past case involving Harry Morgan and a blood-bath crime scene in 1973 involving Dexter's biological mother. Lieutenant Maria LaGuerta braces herself as Captain Matthews blames her for the department's failure to find the Ice Truck Killer and he has her replaced. Rudy and Debra spend some quality time together, and Rudy proposes marriage to the smitten detective. Rita decides to take her children, Astor and Cody, to visit Paul, who has been sent back to prison.
Dexter is quickly becoming a must-see show. In the first season the writers and producers make sure the main plot is never out of focus, even if they deviate from time to time. By the last three or four episodes it's all just on the Ice Truck Killer - and his "other" personality, Rudy. This is the second to last episode of the first season, and it's mostly concerned with plot, but very strong and compelling ones as Dexter keeps looking for clues about the bloodbath and where he actually came from, and Debra is all excited (at first worried-excited then overjoyed) to hear that Rudy "needs to talk" with her about something and that they may go away for a weekend. But it's really all wrapped around the other plots - the stabbing of the officer, the lieutenant's firing, and the general tenor of unease as to the reemergence of the Ice Truck Killer with his "surprise" drop-off of body parts.
It's mostly based around 'when will it happen', as one knows Rudy will reveal himself finally to Debra, a real horrorshow waiting to happen. But it's the anticipation, and Dexter's own quest for the truth, that makes it so suspenseful and dramatic. It's actually one of the best episodes of the first season (not quite as edge-of-your-seat as the finale, but close, certainly in the last few minutes), and you get a sense of the impending tragedy that will befall at least some of the characters.
