>>213787761 (OP)In the original script, the Alien was intelligent and even could talk. He simply knew how the pod worked. Furthermore, he was supposed to kill/rape Ripley (that's why she survived in the end—ever since he saw her fucking the captain, he'd desperately wanted her for himself), and then even fool the ground crew with a radio.
But something else is interesting - Ridley removed the whole sexual motif and deprived Alien of human features, while those funny panties are something you can see on his early storyboards.
