Brett is demonstrating a device he has made.

 

He says it shouldn't damage the little bastard, but it will give him a little "incentive".

 

Ash shows everyone a tracking device he has built, he says it triggers on "micro changes in air density".  Once you are within a certain distance, it will give off a signal.

 

Dallas divides the remaining crew into two groups.

 

Ripley, Parker and Brett begin searching.

 

They soon detect movement.

 

Ripley narrows it down to a locker.

 

They open the door and it's just Jones, the cat.

 

Brett briefly catches the feline, but lets it go again saying "It was just the cat".

 

The others explain to Brett that the cat will probably cause false readings on the motion detector again.  Ripley sends Brett off to find the cat.

 

He searches for a while......

 

He searches high and low.

 

Then comes across a discarded skin from the alien.

 

He cools himself in a trickle of water from above.

 

Then finds Jones.

 

"Here kitty kitty kitty".

 

Jones is about to come to Brett, but the hisses and retreats, He sees something he doesn't like.

 

Brett can't see what's behind him.

 

Until he turns around.

 

The alien has grown, Brett is frozen to the spot.

 

The creature hammers it's retractable jaw into Brett's skull.

 

And carries the crewmember up.

 

Jones watches helplessly.
