Read Notes and Credits.
I'm sorry Freddy and Bonnie relationship in "Papa Bonnie", but this was an adorable moment. If you don't read the fanfiction, well, in chapter 8 Springtrap gets drunk and breaks in the pizzeria. Freddy, Chica, and Foxy are out. Where? I don't know. (They are anthros) In the story, Spring is a bully, so when he breaks in Bonnie tells him to go away. Spring falls down and doesn't get up. Bonnie has to carry Spring back to his apartment. Spring says a paraphrased version of this to Bonnie, and Bonnie asked him what he said. Spring says this to him, and is adorable in the process.
