But how long can he keep hold of it for?
With Billy needing assistance with a house clearing, Rocky offers his help for a cost and Billy offers Karen anything she wants from the clearance in return for her shopping trolley.
Eyeing a doll that Janet may like, Billy is surprised when he finds a wad of money hidden in it. However, Billy later realises that there are two dolls, and Karen has picked up his!
In the café, Billy sees Mia with the doll and finding the money, completely obliterates the doll. How will Karen react when she finds out?
In The Vic, Nancy helps Rocky try and use the laptop. And later, in front of Sonia, Mick scolds a confused Rocky for watching inappropriate things on his laptop. As Sonia and Rocky share a smile at his innocent mistake, he gives her some money hoping to make amends. But it is clear he is far from forgiven.
