In the final episode of Season 5, Ty buys a ring with plans to propose to Amy.
As she is in the hospital, she can't go to her mother's funeral but her father, surprisingly, shows up.
Amy has inherited her mother's gift of being able to intuit the needs of horses and of practicing natural horsemanship.
As a result, he is unable to be by Amy's side throughout her pregnancy, but they communicate frequently through Skype.
Near the end of the season, Ty contracts a potentially life-threatening illness from a tick bite, and returns to Calgary in critical condition.
Jack treats Ty like a son and is very proud of him, especially after he earns his high school diploma and decides to study to become a vet.
