Globalreach was a below par episode. A lot of things the characters do just do not make sense from the president downwards. Worse yet, the storyline is clearly inspired by the classic movie, Seven Days in May, but is nowhere near as good.
Clay Haas is shown up as someone who not fit to lead the task-force. He is a policy hack not an agent.
Claire Haas in all this time has not appointed a vice president leaving the way for the House Speaker Roarke to take over the presidency on some trumped up impeachment charges. Any president fit to lace President Nixon's shoes would had dug up the dirt on Roarke by now and not waited until the last minute. Claire Haas is certainly not the ambitious conniver that she was portrayed as in the first series.
Alex has gone over to the dark-side with the collaborators and at least she has Keyes convinced but Alex herself is being used to cause an explosion at the FBI office.
The team look defeated, most of them have lost the focus for the greater good, Nimah cares more for her sister than what Roarke would do when he comes to power. It is the kind of holes in the plot the show does not need.
