The True Lifesaver Inside Out version

It starts a while after Disgust helps Sadness, she refuses to take Sadness's offer to help her with stuff. Sadness pleads her to do so since it's part of the Emotion Code, but Disgust says that Sadness already owes that to someone else. She reminds her of someone who looked after her and was always there for her, and that she can call that person not just a family, but also home. Sadness figures out it Joy that Disgust is talking about and decides that she's right and goes to talk with Joy.

Sadness goes to Joy's room and asks her if she has a minute. Joy says she does and asks what Sadness has to say. But before Sadness can talk, she begins to cry as she runs over to Joy and hugs her. Joy hugs her with one of her arms and asks what's wrong, and Sadness responds that she's so glad she has her. Joy is tearfully touched, as she wraps both of her arms around Sadness as they embrace each other.
