Blair Connor is a young woman who returns to Heartland with Ty after his Summer away. Ty's girlfriend, Amy, is instantly uncomfortable to see Ty's returned with a female friend, whom he had only referred to as "Connor" in their previous communications. Blair tries to be nice to Amy and her family and friends while she visits, waiting on her boyfriend, Grant, to arrive. The fact that Blair seems to be inseparable from Ty and also has a love of horses, however, doesn't leave Amy feeling any better. The girls face off in a charity horse race, where Amy gets thrown from her horse and Blair disqualifies herself so that she can prevent Amy from being trampled. Amy calls a truce, but it turns out Blair isn't so innocent after all. She reveals to Ty that she has fallen for him and kisses him, but Ty resists her advances and seems glad to see her leave.
