Lisa Swain (Vicky Myers)’s current troubled state of mind in Coronation Street goes back to the death of her wife, Becky, who was also a police officer.

The death of PC Craig Tinker (Colson Smith), who was killed while on duty, was especially hard for Lisa to deal with as it had echoes of Becky’s death. She died while she was chasing a suspect when she was mown down by a getaway car.

Lisa’s grief was compounded by the fact that Becky had been under investigation by the police force’s anti-corruption unit just before her death and this had put a strain on the relationship.

In fact they’d had a huge argument on the day that Becky was killed, something that Lisa deeply regretted later as she never had a chance to apologise and make amends for the things she’d said.

Craig’s funeral, in which his colleagues and loved ones paid their respects, also made Lisa realise that the cloud of suspicion over Becky at the time of her death had meant she was denied the send-off she deserved.

Carla (Alison King) persuaded Lisa that therapy could help her move on from these events. Although sceptical, Lisa gave it a try but was immediately on the defensive when the therapist broached the subject of Becky.

In upcoming episodes there’s an unsettling incident for Lisa when she witnesses a robbery at the Corner Shop and, rather than springing into action, she freezes. She later refuses to talk about this with Carla, who’s puzzled by her actions.

Wanting to be supportive, Carla encourages Lisa to continue with therapy, saying that she’ll feel much better after a few more sessions. Lisa isn’t convinced, but hopes that Carla is right.
