Dans l'épisode 3, Amy se fera manipuler par Chase pour faire un spectacle de dressage qu'Amy refusera au départ mais finira par faire. À la fin de l'épisode, Chase embrassera Amy et elle ne le repoussera pas… Sous le coup de la culpabilité, Amy avouera à Ty ce qui s'est passé.

Ty pardonnera Amy mais il ne lui parlera pas pour autant de son histoire avec Blair… À l'épisode 10, Grant viendra se battre avec Ty parce que Blair a raconté que Ty et elle avaient eu une relation. Amy, sur le coup, sera choquée et ne voudra pas parler à Ty croyant les paroles de Grant, bien que Blair soit venue en personne pour lui dire que ce n'était pas la vérité.
