Tear Jerker: I, Robot
- Gloria almost losing her robot nanny. At age 8. Even Susan Calvin is moved to tears.
- It's later revealed that eventually, Gloria had to give up Robbie anyway due to humanity's paranoia of robots. Granted, Calvin notes that it happened when Gloria was 15, but it's still sad to hear.
- Susan Calvin at the end of Liar! Thanks to the mind-reading robot, she has her hopes dashed hard upon the rocks, and actually breaks down twice, first with shrill laughter, then with bitter tears.
- Herbie's fate even brings a tear to the eye. It was a slave to programming that was trying to do the best it could, and ended up making everything worse in the end.
- When Spooner tells Calvin the story about Sarah.
Spooner: That was someone's baby. 11% is more than enough.
- It's even worse when he reveals his Tragic Keepsake—her necklace. Which means Spooner either saw her body in the morgue, or Sarah's remaining family members gave it to him at the funeral. Poor guy.
- Even more crushing is the almost clinical way that Spooner recounts what happened to Sarah. Listen to his voice. He starts out so calm and factual that one can easily assume he's told this story before, most likely to Sarah's family and to the police after he recovered. Furthermore, he knew the exact percent that the robot calculated when it chose to save him over Sarah, meaning that Spooner probably demanded that the robot tell him why it didn't listen to him, which could only have broken him further. The way he gets choked up by the end of the story is really what seals it because he's clearly been repressing his feelings so hard that it causes the recurring nightmares and Susan's question brought it all rushing up to the surface.
- More tragic on that note—Spooner is someone's baby (his grandmother's) too, but the way he talks about it means he's clearly stopped considering himself as worth anything anymore.
- "Will it hurt?"
- The older model-robots following their orders to protect humans by intercepting the new robots, and getting destroyed in the process. Shortly before that, Spooner looking into the containers, while Lanning's voiceover talks about how the robots tend to cluster together in their containers, in a sort of human way.
- Sonny finally admitting he was instructed by Lanning to kill him. He looks like he's on the verge of tears he cannot shed as he struggles to comprehend his own feelings about being asked to kill his beloved father figure. Spooner's sympathy makes it more poignant.
