Elsewhere, Carol's given a new-found confidence when she starts wearing her wig, but David's unhappy with how she looks and makes his feelings obvious.
Letting Tina move in is something Tosh may be starting to regret when she's reminded just how messy her girlfriend is, and Peter's offered a business opportunity from Alfie.
Charlie suggests it's time Dot moves on, leaving her taken aback, and Pam worries the funeral business isn't taking in any money leaving her husband Les coming up with a money-making plan.
