After he leaves, his phone rings and when Amy goes to answer it, she finds the ring. In Season 6 Ty and Amy come to agreement to wait and Ty gets accepted to vet school.

In the beginning of season one, Ty Borden is a troubled and ill-tempered 17-year-old. He entered "juvie" at a young age after attacking his step-father, Wade, for abusing his mother. For his probation, Ty's probation officer, Clint Riley, made a deal with Marion Fleming that Ty could stay at Heartland Ranch and work there as a stable hand.
When Ty first arrives at Heartland he speeds past Amy Fleming in his truck while she is out riding with a friend, angering her. He informs her that he's looking for Marion Fleming, and Amy tells him that Marion was her mother and she had died.
Ty then meets Jack Bartlett, owner of Heartland Ranch and Amy's grandfather. He, at first, reluctantly agrees to let Ty stay and work at Heartland for the duration of his probation. Jack lets Ty stay in the room above the barn, which Ty was none too thrilled about.
Ty often frustrated Jack when he began working as a stable hand, often slacking off and giving attitude. Jack really became angry when Ty took Jack's truck to go to a party that Amy was also going to when he was supposed to be working.
When he arrives at the party, uninvited, Ty sees Amy's boyfriend Jesse Stanton grab her and thinking that he was hurting her, procedes to get in a fight with him. Amy leaves the party angry and Ty follows. Ty apologizes and offers her ride home, to which Amy reluctantly agrees.
Later, Ty proves that he is not just the punk that Jack thinks he is, when he helps Amy get her horse Spartan to overcome his fear of trailers.
