My love is a red, red Doyle

To celebrate his marriage to his redheaded bride Mal asks Rose to join him on a case about a local greenhouse. As a favour to Mal and Rose, Jake agrees to adopt Rose's role (which is to magically acquire the information needed) for the duration of the case. Meanwhile, Tinny is conflicted about the fact that her step-grandmother is a ginger and whether or not it would be appropriate to kick Rose on Kick a Ginger Day.
