About a week before New Year's Eve Sam committed several home invasions with two of them turning deadly. Dexter was planning to hunt him down for the murders, until Sergeant James Doakes showed up with Sam in cuffs. Dexter was upset at this but moved past it.
When Doakes brings Sam in, the scene is nearly identical to that of when Little Chino is brought in for questioning. Everything from the two flags on both sides, to the outfits all the characters are wearing. The only difference is that Sam is obviously a much smaller individual than Chino (though still taller than Doakes), his hands are in handcuffs where as Chino's hands are free and finally Chino is wearing his signature shades while there is nothing on Sam's face.
