* In a complete inversion of [[Film/TwoThousandOneASpaceOdyssey HAL 9000]], GERTY shows that he is supposed to take care of Sam. "Helping you is what I do." He even comforts him with a pat on the shoulder.
** What brings it close to TearJerker territory is that GERTY is willing to [[spoiler: wipe his memory banks to help Sam escape. He's essentially [[HeroicSacrifice killing himself for his best friend]]]].
* Sam and GERTY's last goodbyes:
-->[[spoiler:'''GERTY''': I hope life on Earth is everything you remember it to be.\\
'''Sam''': Thanks, Gerty.\\
'''GERTY''': Are you going to be OK?\\
'''Sam''': Of course.\\
'''GERTY''': The new Sam and I will be back to our programming as soon as I have finished rebooting.\\
'''Sam''': Gerty, we're not programmed. We're people. Understand?]]
* The last-minute resetting of the harvester coordinates, which ends the satellite blockout: even if Sam 6 didn't make it back, Sam 7 would now have a chance to find out what's going on.
