With T'Pol and Trip hostage, John Frederick Paxton demands that all aliens leave the solar system or else he will destroy Starfleet Headquarters. With that warning and the clock counting, Starfleet orders Archer and the Enterprise to Mars to take out the weapon threatening Earth. Meanwhile, the cloned baby of T'Pol and Trip is getting sicker and time is running out for her as well. Imprisoned, Gannet Brooks reveals to Travis that she is a secret member of Starfleet Intelligence. She has been assigned to find a Terra Prime operative working undercover on the Enterprise. With the clock ticking, the future of the planned Federation lies in the balance. Written by timdalton007

When Paxton fires the beam at Earth's moon, it strikes it immediately. Even at the closest possible distance between Earth and Mars, it would take a little over 3 minutes for the beam, traveling at the speed of light, to reach the moon. The same is true for when the beam strikes the San Fransisco Bay later. (This is not a goof: a "verteron" is a particle that travels faster than light.) See more »


[T'Pol has found out that Paxton is suffering from Taggart's Syndrome and treating it with an alien therapy]
Commander T'Pol: The very thing you're warning Humans to avoid is what's keeping you alive: alien knowledge, freely shared. You're not only a terrorist, you're a hypocrite.

Nicely Done/Not Simplistic
31 March 2017 | by HitchcocSee all my reviews

So our overblown zealot had feet of clay. Good. This is an excellent episode with great pacing and a story of love and loss. It also sets up much of what happens next for the lineage of the Enterprise. Suspicion and hatred for those things we don't know is the most destructive force we deal with. It would be nice if our leadership would take a hard look at themselves at times. Yes, there are dangers. Address them. But don't paint the whole world with the same brush. Excellent concluding two part episode. One thing. I wonder how many sea lions were lost when that heat ray hit the water?
