Sally (Sally Dynevor) is currently in the dark over the recent revelation that Tim needs triple heart bypass surgery after some concerning test results.

Kevin encourages Sally not to jump to conclusions and suggests that she should speak to Tim.

When Sally does confront Tim and accuses him of infidelity, he still feels unable to tell her the real story – only fuelling her suspicions further.

Sally's theory grows when Shona Platt (Julia Goulding) tells Abi Webster that Tim has been spending lots of time with Aggie Bailey lately.

Abi (Sally Carman) passes this gossip onto Sally, who starts to wonder whether Aggie is the other woman.

Tim plucks up the courage to tell Sally the truth but suddenly experiences chest pains and collapses to the ground.

Sally is stunned to finally discover the truth about what Tim has been going through. How will she feel about his secrecy? And will Tim be okay?
