When Jack relents and allows Tim to visit Heartland, the simmering sibling rivalry between Amy and Lou heats to a boil. Hoping to impress Tim with her managerial skills, Lou is heartbroken when she realises that Amy and Tim share a deeper bond: their love of horses. After Lou witnesses her father pushing Amy to take a risk with a difficult cutting horse, she begins to wonder if Tim has really changed after all.
Meanwhile, Jack takes Lisa Stillman fishing on their second date and can't believe his luck after catching a real beauty so late in the season. Jack's love life may be in good order, but Ty becomes more and more frustrated with Amy's refusal to talk about what is happening between the two of them.
