Aside from the near-constant sexual chemistry which hums louder than any sewing machine, Carla and Peter's working relationship has been going well.
But all good things must come to an end (apparently), as Peter gives Carla some shocking news in the coming weeks.
Carla is caught off-guard when Peter announces he no longer wants to work with her at Underworld.
The TV Times autumn preview reveals that Peter has grown tired of working at the knicker factory and decides it's time to move on.
Realising it's not the job he thought it would be, and believing he's not crucial to the factory as he knows nothing about sewing, he starts to look into other business ventures...
And when he sees a snooker club up for sale, Peter decides to pursue it.
However, in order to fund the new club, he has to sell his share of Underworld.
Well, that was short-lived!
And when Peter sells his share of the factory to a familiar face, Carla is left livid at being kept out of the loop.
Shocked at her new business partner and doubly upset that Peter did the deal behind her back, their relationship is left at an all-time low...
Not great with Nick Tilsey back on the scene!
