Mia, Lee, and Connor drive home in stunned silence after the killing. The tension, palpable.
The next day, on the outskirts of Blaenau Ffestiniog, garage owner HEFIN (Bryn Fôn) discovers the body of his lodger dumped in the mechanic’s pit at the petrol station and calls the police.
DCI John is informed about the victim – ex-prisoner Siôn Wells, a lodger in a neighbouring property, a man trying to turn his life around.
Cadi suspects there may be a link with the Ellis case. Hefin tells her about the previous day’s altercation on the forecourt, and Cadi presses him for a description of the youths involved.
Describing the ring-leader as a sixteen-year-old female with dark hair, Cadi begins to suspect it might be the same girl she questioned at the school the day before.
Issuing a warrant for Mia’s arrest, all efforts to trace her fail.
Meanwhile, Lee is intercepted by police as he tries to leave town, while Connor – unable to make peace with his actions – wanders to the lake alone. Guilt-stricken and desperate.
