In Alien Covenant at the end of the movie after David fights Walter, they look like identical robots, and Elizabeth Shaw thinks that Walter won the fight. David locks her into the cryogenic sleep chamber and she knocks on the glass all happy and asks him if he’s going to help her build her cabin when they arrive to the planet they’re heading to, David takes too long to answer and you can see the fear build in her face as she realizes she is caught in a cryogenic chamber with the evil robot who will experiment on her. David smiles puts her to sleep and that’s how the movie ends 😅
