What went right: Chase has been more closed off than others, and we found out why this week. His parents' divorce did a number on him, but he showed personal growth talking to his family. JoJo witnessed all of that and was probably given hope from hearing him talk about his pain but also his feelings for her.
What went wrong: He actually spent the least time with JoJo because he spent so much alone time with each parent. It was good because we got to see where Chase was coming from and his growth. But JoJo might not feel like the two connected as much as the others.
