Admittedly, I’ve been guessing that the end of Dexter this season will have something to do with the murder of the Trinity Killer. But over the past few weeks as Dex has infiltrated the man’s normal and staid life. Viewers should by this point be painfully aware of the fact that Arthur moves in and out of sanity, which can seemingly be brought on by anything at all – even a family eating lunch. But as Dexter continues to create a more in-depth and realistic life as Kyle Butler will there be a moment that the Trinity Killer realizes what is going down and puts an end to it?

This week’s episode – “Road Kill” – finds Dexter believing that Arthur’s trip to Tampa is only going to lead to another killing adding to a thirty year spree that no one can fully account for or understand. When the title character figures out how to skip town, his act becomes an all too genuine and slightly terrifying exercise in fooling those that are around him.

It all harkens back to earlier season’s before Dex was family man and able to move in and out of polite society with less trouble, but still exploiting other’s perception of him as just a nice guy. With the family scenes, it may have become easy for viewers to forget that Dex is still a killer – and a good one. But the daily interactions that he’s been having for most of this season, including barbeques, buying presents for kids and the like, have only been in an attempt to camouflage himself in polite society.

After boring his boss to death – metaphorically, of course – Dex head’s home to work on the wife. It’s a success on all fronts. But the character hasn’t discussed catching a ride with Arthur, so when he shows up as the Trinity Killer is preparing to leave, there’s a bit of a verbal sparing match that transpires ending with Dex getting in the car.

The reticence of the Trinty to be fully rude and dismissive belies some of the mental short comings that he’s soon to reveal. And after Dex explains the fact that he’s accidentally killed a man – although in this rendition it’s a hunting accident and not a ritual – Arthur seems to understand and relate to Dexter Kyle better. Of course, this untruth most likely leads to a scene a bit later when Arthur completely losses it and heads off to this childhood home, pushing past the current owners and making his way to the bathroom, where he apparently witnessed the death of his sister so long ago.

More erratic behavior follows with Dexter needing to remove his travelling buddy from a restaurant. Dex, though, even after figuring that he has a great deal to learn from this monster concludes that killing him in Tampa is the right thing to do. Of course, Arthur has a different plan which only results in some confusing voice overs and the morality of the title character becoming an even more tangled mess than it was before. So, who’s the bad guy?
