Northern Exposure - Season 5 Episode 23
Blood Ties

Though he promotes it on the air, Chris has reservations about making a donation for Maurices blood drive. Ed discovers his rare blood type is shared by another person in town, so he hires a P.I., Renaldo Pinetree, to dig into her past and find out if she is her mother. Maggies old "tiller mate" from Grosse Pointe comes to Cicely after her affections and he offers Joel the incentive to leave Cicely for good. Joel loses his touch for drawing blood as Cicely nears the amount Maurice needs to win his bet with a neighboring town.
