Grace Black (Tamara Wall) and Rex Gallagher (Jonny Labey) toasted to the end of the Roscoe era after seemingly getting rid of Robbie (Charlie Wernham), believing him to be their mole.
Maxine subsequently filled Liberty Savage (Jessamy Stoddart) in about how she’d split from her boyfriend, revealing all about his undercover duties within earshot of DI Banks, who subsequently notified Grace about the existence of a mole.
Robbie, meanwhile, had no idea that Grace and Rex suspected him of being an undercover cop and, as he prepared for a date with Maxine, he was confronted by the two, who held him at gunpoint.
His fate remains unknown but Grace and Rex were pretty adamant that they’d solved the issue of the mole in subsequent scenes, as they toasted to the end of the Roscoe age.
Grace set a trap for the mole, planting a tracker in a bag she gave Maxine, who subsequently met with Robbie at the folly.
