Guard One: “Is it distressed?”

Guard Two: “I... don't think so.”

Guard One: “Then why is it making that noise?”

Guard Two: “The translator identifies repeating pitch structures. Possibly ritual behavior.”

Then it suddenly stops.

From inside:

“WAIT. Do y'all have mind-altering substances?”

Translator finally has enough English mapped to produce:

Both guards slowly turn and stare at one another.

Guard One: “It hasn't consumed water in seventy-eight thousand years.”

Guard Two: “Correct.”

“It crossed interstellar space using its feet.”

“Correct.”

“It is currently standing naked in a hazardous solvent.”

“Correct.”

“And now it wants drugs.”

Long pause.

“...correct.”

Captain over comms:

“Under absolutely no circumstances give the unknown immortal biomechanical organism psychoactive compounds.”

You, hearing the vibration through the wall:

“HEY, I HEARD THAT.”

Guard One: “IT CAN HEAR THROUGH THE BULKHEAD TOO?!”

Then you emerge from the shower utterly refreshed, presumably having discovered their equivalent of a towel:

“Okay. That was fantastic. So. About those substances.”

Xenobiologist:

“Why would an organism engineered to survive tens of thousands of years require chemical alteration of its neurological state?”

“Require? No no.”

gestures philosophically

“Sometimes consciousness needs to shut the hell up.”

Translator spends twelve seconds thinking.

INTERPRETATION: SUBJECT OCCASIONALLY DESIRES REDUCED COGNITIVE ACTIVITY.

Science officer:

“...actually, I understand that.”

Captain:

“DO NOT ENCOURAGE IT.”
