ARTOO projects a schematic hologram of the castle. He highlights the new factory building at the base of the outcrop.
THREEPIO: He says that this structure houses the pump station, which will need to be shut down. The station’s computer systems are not accessible from here ; it seems they are operating on an independent circuit.
Suddenly, ARTOO whistles and beeps, and highlights a tall spire on the castle hologram.
LUKE: What’s that?
THREEPIO: He says Princess Alana is being held in the top of the north tower!
LUKE steps forward.
LUKE: Artoo, see if you can disrupt all communications down here.
ARTOO beeps, and his claw arm rotates in the computer socket as he carries out his orders.
