Season 10
An injured Ghost unexpectedly reappears years later at a time when Amy is worried that something is seriously wrong with Ty who is currently in Mongolia saving bears. Ghost's appearance concerns Amy as, combined with her bad dreams, the last time she had seen Ghost was when Ty had had his motorcycle accident. Amy and Jack successfully treat Ghost and Amy talks Ty who is apparently fine. Amy tells Ty that when she had gone back to see Ghost again, he'd disappeared. After hanging up with Amy, Ty suddenly collapses in the same way as Ghost did, seriously ill. Ghost returns shortly after Ty's collapse and paws at the ground in front of Amy, seemingly trying to signal her that something's very wrong with Ty before walking off again. Aware of the connection between Ty and Ghost, this greatly deepens Amy's concern which had been alleviated by talking to Ty.

As Ty's recovering in the hospital, Amy and Georgie encounter Ghost again who has recovered from his injuries. However, he runs off when Georgie approaches him and Georgie becomes convinced that he keeps coming back because Ghost wants a home with them. Georgie convinces Jack to help her catch Ghost in an effort to gentle him herself, but Ghost ignores her attempts and constantly tries to escape his corral. Finally, recognizing that Ghost is unhappy, Georgie lets him go. A short time later, as Ty and Amy are enjoying their newborn daughter, Ty hears a noise out the window and discovers that Ghost has returned again, apparently to check up on them. Ghost approaches Georgie and allows her to pet him, much to her surprise and delight. Georgie reassures Ghost that Ty and Amy are fine and she understands if Ghost wants to leave again. Watched by Ty, Amy and Georgie, Ghost departs once again.
