Heartland (2007)

Season 5: Episode 1

Tim is having no luck tracking down Miranda and Shane since she dropped the bombshell that Shane is his son... until Shane --on his own-- surprises everyone by just showing up at Heartland. And Mallory entertains the idea of going with the recently-single-again Jake to the Spring Fling. There is however --as you might expect with Mallory-- a "but" attached.
