I think because Carla herself thinks she is to blame now so she may have had then a few drinks before going to sleep on the sofa even though the viewers didn't see this, she did tell Roy she couldn't remember the events of the fire or if she outed the candle
Tracy was quick to start blaming Carla as she knows it was her fault so add more fuel to the fire so to speak by telling Leanne it was Carla's fault too as she was drunk
Where did Zeedan get the rock he was going to use on Carla's car, their don't seem to be any lose rocks around the street![]()
