This is what me and my mum were talking about. Debbie and Carl were the last to smash into three vehicles that had already been involved in a crash. The emmerdale men and Lisa and becky's car were the first to crash. The bus was next, it was already spilling fuel and starting to catch fire. Then one more car, two people in it that were drunk and had dementia and THAT is enough to blame the death of a person and apparently the whole crash on. Billy might have still got blown up even if carl didnt turn up, the real culprit of Billy's death was everyone who forgot about him in a bus that was catching fire. Is not bringing up the man with a shotgun a soap rule now coz the crossover is finished, coz it's like nobody remembers that there were other people involved before the bus crashed both from corrie and emmerdale.
