In the build-up to the fire, Katie makes the mistake of taunting Andy's brother Robert as she continues to threaten him.
Still convinced that Robert is having an affair with a mystery person, Katie warns him that she will make it her mission to become as friendly as possible with his fiancée Chrissie White.
A furious Robert takes Katie's taunts as a threat, knowing that she wants to find a way to turn Chrissie against him for good.
When Robert heads off in an angry mood, it's not long before Katie and Andy realise that the caravan at Wylie's Farm is ablaze.
Having moved all of their belongings into the caravan, the pair watch on in horror as the fire leads to an explosion and their plans for the future are ruined.
