They film in NYC. NYC (and everywhere north of the South) has been hit by multiple blizzards. Gonna be a few snowy episodes. Dat was the realest snowz.
Samaritan would pretty much have the same data retrieval ability as The Machine, except that it would be totally accessable by human hands. Someone with access can sit there and learn everything about everyone. Including locations of people in hiding, unless they are so far off the grid that they live in a cave and eat from the land.
Basically, at that point, Decima/Greer, who knows enough that there is a Finch/Reese team, could just ask Samaritan who are these people and where do they sleep, eat, work, etc.
It could even get crazier, if either of these machines were able to access launch codes, drones, airplane autopilot systems, or any other numerable ways to wreck havoc.
