Stevens finds an article about the death of Tom Reynolds. The article is titled: "Silesian student drowns tragically" yet at the end of the article it says that his cause of death is unknown. The article states as the beginning that he drown and it also states the water was very cold so his cause of death was pretty obvious.
When Nichols and Stevens are riding the Staten Island ferry, Nichols hair is blowing in the wind and a mess in the wide shot of him and Stevens standing together. In the closeup shot of Nichols talking his hair is neatly combed without a single strand blowing in the wind. Then in the closeup shot of Stevens her hair can be seen blowing in the wind yet when the shot cuts back to Nichols his hair is still neat and perfectly still.
Near the end of the show Nichols and Stevens are seen riding the Staten Island Ferry, going to Staten Island to continue their investigation. After arresting a suspect there, they are seen getting into their unmarked police car. Cars have not been carried on the Ferry since September 11, 2001.
