GATTACA by Andrew M. Niccol - The Script Source

102.
Under the Investigator's watchful eye, Detective Hugo
withdraws the syringe and immediately inserts a small amount
of the blood into the portable analyzer he wears. Naturally,
it confirms that Eugene is Jerome.
Irene does her best to conceal her shock. Hiding his
frustration, the Investigator distractedly tours the room
while Hugo packs up his gear. The Investigator idly toys
with the telescope pointed out of the window.
Next he wanders towards the closet and reaches for the
doorknob.
INVESTIGATOR
Mind if I take a leak?
EUGENE
As long as you don't do it in my
closet. (nodding to the other
side of the room)
Over there.
INT. JEROME'S CONDOMINIUM - BATHROOM. DAY.
The INVESTIGATOR immediately pulls a specimen bag from his
jacket pocket and closely inspects the stainless steel toilet
and sink. They are both spotless. The shower stall is also
scrupulously clean. He flushes the toilet and exits.
Lost in thought, the INVESTIGATOR approaches the closet again
and wheels out Jerome's upright vacuum cleaner. He is
disappointed a second time to find no vacuum bag inside. The
Investigator returns the vacuum cleaner to the closet and
produces a mini-vac from Detective Hugo's crime bag.
May I?
INVESTIGATOR
(to Eugene, referring
to their mini-vac)
EUGENE
Clean the whole house if you want.
IRENE
(taking Eugene's lead)
Actually, the kitchen needs doing.
The Investigator switches on the mini-vac to take a specimen
from the floor, then promptly kills the machine.
