Nitpick: After Enterprise rendezvous with Degra's ship, Trip says that he hasn't slept since the attack, and T'Pol replies that that was two days earlier. However, in the previous episode, "Damage", Degra's message, which was only found following the attack, instructed them to meet him in three days.
Degra: The Reptilians are correct about one thing, Captain. You have an impressive facility for deception.
Archer: Erasing your memory probably wasn't the best way to earn your trust.
Degra: Probably not.
Trip: Every time I start I hear myself sayin', 'What a fine young woman she was. How... how smart and full of potential.' And I realize I'm not thinkin' about Taylor at all. I'm thinkin' about Elizabeth. So many people dead. I tried not to see her any differently than the other seven million, so I spent the last nine months tryin' to pretend she was just another victim. But she's my sister, T'Pol. My baby sister! I envy you Vulcans.
T'Pol: You think that the loss of a colleague or a friend doesn't affect us? It does, but if we give in to those emotions, they overwhelm us. You're the ones to be envied.
Degra: These scans are remarkably detailed for a military vessel.
Archer: Enterprise was designed to be a ship of exploration.
Degra: If we're successful, it will be again.
Archer: We're in bad shape. I can't deny that, but we're still in one piece. Enterprise is a tough ship. She took more then anyone could ask her to and then some. And so have all of you. I wanted to say thank you. I only wish I could thank the eighteen crewmen who were lost. Like you, they understood how important our mission is and they accepted the risks. We came into the Expanse not knowing what we'd find. With no one to rely on but ourselves, but we're going to succeed. To accomplish our mission. For everyone on Earth who's relying on us and for the eighteen.
Trip: It'd take at least a thousand starships like Enterprise to blow up an entire planet.
This is likely a reference to Star Wars: A New Hope. In that movie, upon discovering that the planet Alderaan has been destroyed, Han Solo begins to say that "It would take 1,000 ships with more firepower than I've..."
