You tryna send me some of that melanin , I ' ve seen all my old white relatives and I ' m not a fan of what I ' ve seen . <| sep |> Always something to discover by rewatching . As you guys described correctly , having a killer as the person of interest naturally rises the question about redemption and who is worth saving . Mr . Tall , Dark and Fierce quote Fusco in this episode understands that from the beginning He is a killer , so am I and that provokes Harold to use Roots term of Bad Code which John doesn ' t understand first , but asks about at the end . your quote Roswell . John clearly makes comparisons to his own life when he talks to Annie at the end You gave him the strengt to walk away from the only life he knew , make him better . Reminds me of the way he spoke about Jessica the one person that connects you to the world . And because this is all about killers , we get a lot of atmosphere shown to us by the actors with angry stares and fierce and threatening whispers , Jonathan Tucker can do it as well as Jim Caviezel . But the look an Reese face in the last scene , when the hitman opens his door is priceless . Two further things worth mentioning The music in the scene when Riley calls Annie the first time on the phone is a single violin playing a melancholic tune , must be Irish and those are Irish people right ? And then the memorable quote You got a detective in your pocket ? More likely on my back . nice one !
