Kathy was being abused by her husband, Gavin, to the extent that marital rape even occured in their marriage. Gavin was also a criminal in South Africa and had an affair with other women. This bit wouldn't be implausible because ever since Pete Beale, Kathy had a history of choosing wrong'uns.
Kathy then had a mental breakdown and she and Ted tampered with Gavin's car and told her brother Ted. Ted gave her a fake passport and she left South Africa. Again, this wouldn't be implausible because there could be a history of mental health problems in the Hills family (Kathy's father used to be abusive, Ian had a mental breakdown and perhaps Ben and Donna also had mental issues), which could be something to explore. Also, Sam Mitchell reentered Britain with a fake passport. Ted then identifies Gavin's mistress as Kathy which is why she is 'dead'. Kathy then tells Ian and Phil that it was 'witness protection' because Gavin was a criminal and the South African police conclude that the car was tampered by a fellow criminal. At the end of the day, it is a soap and you can suspend reality if it is not too outlandish. This could lead to Kathy having a dark secret and a whole new Beale/Mitchell storyline.
