DOTTY Cotton leaves the square in fury after finding out Dot's home was left to Sonia Fowler.
The troubled teen was confident she would be getting her grandmother's home and even made plans to travel with the money.
But she received a nasty shock in Friday's episode of the BBC soap when the will stated Dot's home was left to Sonia instead.
Full of rage, Dotty covered the house in alcohol and prepared to set it alight with a match and Sonia inside.
An angry Dotty said: "She told me she loved me. She told me I was important to her, but it was all lies..."
"I'm going to burn it down. And if you don't want to go up in flames, I would leave right now."
