This final 2-parter gathers up everything that has happened so far in Season 4 and dumps it into two beautiful Episodes.
Speaking of Beautiful, it's Travis' Ex, the lovely Johanna Watts as Gannet Brooks. A "So Called" Reporter, you'll find out why later. Peter Weller is yet another reactionary Meathead Sean Hannity-type who has done some very bad things.
Harry Groener from TNG "Tin Man" is a future politician, "Nathan Samuels", who used to be a member of the Xenophobic Group "Terra Prime". which is a lame future version of the lame "America First".
As Samuels tries to preside over a meeting of ambassadors from several planets, the Brietbart of the future has been soapbox- spouting, and people eating it up because of, of course, the Xindi wiped out 7 million people. Isil hasn't quite caught up with that yet, although Germany surpassed it previously, and people forget that Nazism started with Xenophobia. Then came the Deportation forces and the Concentration camps.
So, this preliminary meeting of the "UFP" does not bode well, because of this Breitbart style Xenophobia spreading. Phlox had been targeted during "Home" by a redneck in a bar.
Other things that didn't help much were a woman appearing and dying in front of everyone from a Disruptor blast, cryptically saying "They are gonna kill 'her'", whoever 'her' is.
And then it appears that Starfleet Security wants to shovel it all under the carpet. Archer finds a way around it, and Malcolm must needs meet his "Section 31" associate once more.
This 'Sode is a bunch of puzzle pieces being creatively put together, and it's marvelous. But just wait until the Conclusion!
