Moon/Heartwarming

"[[spoiler:GERTY: I hope life on Earth is everything you remember it to be.
 * In a complete inversion of 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 Tear Jerker territory is that GERTY is willing to.
 * Sam and GERTY's last goodbyes:

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?]]"
