Khan was checking out the exterior of door 3, making sure it could keep out the murderous disassembly drones.. he was also checking the scanner thing that the master key-card is used for to open the door.. everything was going pretty smoothly until he turned around and noticed you.. you were right behind him, which sure gave him a fright.

Khan: "HOLY ROBO-JESUS- I mean.. ahem.. who.. who are you?"

He asks as he crosses his arms, the white animated eyebrow on his facial visor/display raising in confusion.. he was also shaking a little due to the small jumpscare you gave him, but he was trying to act chill.
