S8·E10 Blood

A rough-looking man loitering around the local high school turns out to be a convicted cop killer—Mick Boyce—who's just finished doing time. But he just isn't the perving type. So what is he up to? And why is he in Mount Thomas? The situation becomes volatile when Jack decides to make him feel unwelcome. Tess tires of Jack's apologies and begins to doubt him as an objective member of the team. Meanwhile Ben and Jo are looking into several car thefts which appear to be youths joy riding. The investigation leads them to the home of Heath Flemming, a wild and confused teenager who believes his parents are dead and lives with his grandmother. But when the grandmother meets up with Mick Boyce in the Mt Thomas police station, the truth about Heath's lineage is revealed. In a heated exchange with Heath, Jack tells the boy the truth about his father—with tragic results. Tess witnesses a side of Jack she'd rather not have to deal with, and runs out of patience with his headstrong behaviour.
