Nitpick: Soval tells Shran that the Vulcan fleet is at the star Regulus. This could not be true because it was established in the episode "Home" that Vulcans do not venture far outside their own system. Regulus us over 63 light years away.
T'Pol's disease, contracted in season one's "Fusion", is finally cured by T'Pau.
T'Pol: Captain, you need to rest.
Archer: Thanks, but I'll be fine.
T'Pol: The atmosphere is thinner than you're used to. If you don't stop soon, you'll collapse.
Archer: If you need a break, T'Pol, you should say so.
Kuvak: The people of Vulcan are in your debt. Peace, and long life.
T'Pau: You may be witnessing the start of a new era; not only for Vulcan, but for Earth as well.
Soval: The Minister intends to pursue a less aggressive policy toward your people. The High Command will be dissolved.
T'Pau: You'll no longer have us looking over your shoulder. It's time for Earth to stand on its own.
Archer: We're ready.
Soval: You must know that torture is rarely effective against Vulcans. Our mental disciplines allow us to suppress pain.
Shran: Our security division has had a great deal of experience extracting information from Vulcan operatives. This machine doesn't cause physical discomfort. It uses a neurosynaptic field to lower your emotional threshold. (Soval groans) How do you feel? I've seen Vulcans who were broken by this device. They were never the same again. I have no desire to see that happen to you. Where is your fleet?!
Soval: I told you! Our ships are assembling near Regulus! Release me!
Shran: I can't. Not until I'm certain you've told us the truth.
Soval: Then I suggest you increase the setting and get this over with.
Shran: Tell Archer that's two he owes me!
Soval: (to Shran) His name means "fool" in our language. Just like yours will in Andorian!
