* After he finds out that he's going to lose his intelligence, Charlie goes to visit his mother before it happens. Suffering from dementia, she doesn't recognize him first, but when she does, she's proud of him. For the first time in his life, Charlie feels accepted by her. He also meets his sister, Norma and sees that she became a kind and caring woman, unlike the SpoiledBrat he remembered.
* Near the end, when [[spoiler: Charlie's intelligence is on the decline]], and he goes back to the box factory. Specifically, when one of his coworkers (who was hired after Charlie had quit) started making fun of him in a manner resembling his treatment at the start... then Joe Carp stepped in, gripped the guy's shirt, and told him that if he did it again, he'd break his scrawny neck.
