Since discovering that Craig Tinker could place him at the Rovers on the night of the devastating fire, Karl has been on edge and is ready to go to great lengths to keep his dark secret under wraps.
"(Karl) could not believe that a little kid like Craig could ruin everything, he thought he got through it all," explained John.
"Suddenly there's this kid who has actually got something on Karl, he finds it incredibly annoying and frustrating and his anger starts to come up, but he also knows there is a way of controlling a kid which he thinks is quite easy.
"Basically he scares him and he thinks it's worked."
Sunita's killer believes he has managed to keep Craig quiet for good by threatening to kill his mum Beth if he says anything about that night.
But there is nothing he can do about Jason and Dev's mounting suspicions.
"Jason and Dev realise there is something very strange going on between Karl and Craig," said John.
"They begin to question Craig and gradually, because he is a young kid, he begins to breakdown and they find out information that Karl would kill for them not to find.
"He knows that very soon something is going to fall so he has to get the hell out as fast as he can."
Karl decides to borrow some money and books two tickets to Barcelona for the day of his wedding to Stella.
"He times it so that basically Stella and Karl will have one drink at the reception and then they will have to go.
"It has to be timed to perfection for him to escape Weatherfield and never come back, with his prize Stella.
"Will he make it? You need to watch and see."
