Darth Vader: (walks down the platform and greets Director Orson Krennic) Director Krennic.
Orson Krennic: Lord Vader.
Darth Vader: You seem unsettled.
Orson Krennic: No, just...pressed for time; there's a great many things to attend to.
Darth Vader: (sarcastic) My apologies. You do have a great many things to explain.
Orson Krennic: (looking nervous, as Vader paces around him) I delivered the weapon the Emperor requested. I deserve an audience to make certain he understands its remarkable...potential.
Darth Vader: Its power to create problems has certainly been confirmed. A city destroyed, an Imperial facility openly attacked?
Orson Krennic: It was Governor Tarkin who suggested the test.
Darth Vader: You were not summoned here to grovel, Director Krennic.
Orson Krennic: No, it's...
Darth Vader: There is no Death Star. The Senate has been informed that Jedha was destroyed in a mining disaster.
Orson Krennic: Yes, my lord.
Darth Vader: I expect you not to rest until you can assure the Emperor than Galen Erso has not compromised this weapon in any way. (turns and walks back up the ramp)
Orson Krennic: So...I'm still in command? (Vader stops walking, his back facing Krennic) You'll speak to the Emperor about... (stops breathing, and falls to the ground. Vader turns around with his arm partly raised, showing that he's Force-choking Krennic)
Darth Vader: Be careful not to choke on your aspirations, Director. (releases his Force grip and walks away, leaving Krennic gasping on the ground)
