But will his plan work?
When Carla suggests she might return to work, Peter calls at the factory to pick up some files for Carla and explains that she hopes to be back in a few days.
Calling at the flat with the file for Carla, Stephen waits for her back to be turned before spiking her glass of water with LSD. As Carla starts to feel dizzy and disorientated, Peter tells Stephen he’s going to call the doctor.
When Stephen informs Elaine that he can now afford to repay her loan in full, she eyes a new flat in Redbank.
Dismayed to find Carla fighting fit and almost ready to get back to work, Stephen asks Sarah to convince Carla that her mental health is still too fragile for her to return to work. Will he get Sarah on side?
