Coinciding with a storm hitting the eastern tri-state area which may require evacuation of coastal residents, the machine has not provided any numbers in three days, leading Reese and Finch to believe that there might be something wrong with it, especially what Stanton may have done to it prior to her death. When the machine does provide a number, it provides six men simultaneously, five who are officially missing or have ceased their electronic footprint. Reese and Finch decide to focus on the sixth, Jack Rollins - Finch at his New York apartment, Reese at his rented home on Owen Island just off the northeast tip of Long Island - while Carter is tasked with finding out more about the missing or off-the-grid five.

When the fisherman is dragging Reese towards the water and Reese regains consciousness, Reese grabs an oar. Reese's feet are bound together. In the camera switch, Reese is instantly on his feet swinging the oar horizontally at the fisherman's head. Reese could not have possibly gotten up instantly, let alone with his feet bound with the fisherman holding the rope to his bound feet. See more »


Special Agent Alan Fahey: The question isn't who I am. It's who you are. I watched you all night. I can always spot an impostor. I spotted you. Are you like me?
Harold Finch: You have no idea. You're an amateur at this.

"A" for effort, "B" for results
26 September 2014 | by A_Different_DrummerSee all my reviews

I respect this writing team.

To spend so much time establishing a formula that viewers are hooked on, and then to (occasionally) toss the formula under the bus and go for something new, takes guts. Bully for them.

Here the writers turn an entire episode into a "stranded at the motel" story. Not original. Been done both on the Broadway stage and in Hollywood movies probably dozens of times. But it is fun and new and interesting.

Jim Caviezel looks lost without his suit! Wow. Shows you the power of repetition.

Only reason I did give it a higher rating is that I saw the plot twist before the half way point. But, to be fair, I have seen a lot of film and TV.
