Enter the interrogators' room

You enter the room. The guard turns on you. "What do you want, civilian? Do you have any information about the missing Sith uniforms? Make it quick!"

"Uniforms? What are you talking about?"

"You're awfully curious about this... maybe a little too curious! I think you know more about these missing uniforms than you're saying!"

You try to bluff, but the trooper's suspicions aren't allayed, and he quickly comes to the conclusion that you must be part of the Tarisian underground. He and his fellow troops draw their weapons. You're **** to fight all three off, but manage to gain the upper hand. The fight ends with you slitting the commander's throat, and dropping him to the floor.

You search the room; it seems the Aqualish didn't have any Sith uniforms stashed here after all. However, you and Carth take uniforms from the dead troopers, and, after cleaning the blood off them at your hideout, you have some servicable disguises to get past the elevator guard.
