"Let me handle this one." Alor presses the button to talk back to the landing coordinator. "RC-1138 here sir. Returning with RC-1139, RC-1140, and RC-1141. Did Lord Vader not make you aware we were coming?"
The voice comes over the intercom again. "RC-1138, I don't have your flight in our schedule. Please transmit your landing clearance if you actually have been sent by Lord Vader."
Chandra goes up to the cockpit and listens to the transmission from the planet. She hands Alor a data chip, "transmit this," she says, "these codes should be valid"
"We're a special commando unit sent to kill jedi. We wouldn't have a scheduled landing. We had to steal a ship to get back here. I have the jedi's lightsaber and would be more then willing to show it to you over the holocam."
Alor starts transmitting the codes handed to him by Chandra. "I'll send you the codes, but I'll be informing Lord Vader of your distrust of his Commandos."
