Corrected entry: There is only one real human left aboard Star One. Instead of killing her on sight, the Andromedan invaders prefer to tax their own energy maintaining human forms to deceive her instead. Servalan views her Federation personnel file back at Federation HQ, and then the shot fades to the woman herself, on Star One, not only in exactly the same pose but wearing precisely the same clothing, makeup etc. as in the personnel file. That's what I call an up-to-date records system.
