An absolutely exciting episode of Dexter this week and a high point for the season!
Dexter has gotten right in with Trinity's family and discovers all is not as rosy behind closed doors as he first thought.
There were some very, very dramatic scenes when Dexter joins the Mitchells for Thanksgiving dinner after he promised Jonah he'd be there. Jonah had damaged his car and was clearly frightened of his father - rightly it transpires when Arthur breaks Jonah's finger as punishment. Turns out Trinity/Arthur is as much a monster at home as he is when he's out killing people.
The dinner turns ugly and we get the most gripping and exciting scene of the season, and one of the best of the entire series, when Trinity attacks his own son. Dexter, having come a long way emotionally since season 1, lets his emotions take over and he grabs Trinity to prevent him strangling Jonah and drags him into the kitchen where his own inner monster reveals itself..
The incredible tension make this episode one of the best in the last season!
