This series was getting better with each episode and was starting to find its way. Once again, the plug is pulled and we the faithful viewers are left hanging. This one was solid all the way until the shocking end.
The terrorist and Gideon came face to face. Ada made a terrible mistake and the terrorist has blackmailed into doing some of his dirty work and when she called his bluff, HE called the FBI. Of course, the FBI is more interested in making an arrest than waiting until she helps stop the terrorist. That part was very unlikely for the FBI. A big shock in the ending is about Mayor Salgado.
This is another show where I wish the network would allow one more episode to wrap up all of the story lines which were really starting to get interesting. Being professionals, I am sure they would have given it their all like the cast did on Person Of interest.
Good luck and nice try for all involved.
