Jack was supposedly dying of cancer. He looked pretty good for a man with only days to live. In reality, just before the end, you would not be in a state to get out of bed, let alone stroll down to the Rovers for a pint. If terminal cancer sufferers could simply attend a party and then doze off in a chair then that would be a nicer way to go than the drugged-up reality in some hospital or hospice. The manner of his going would have made more sense if Jack had died of heart failure. That said, another great character has left the street. Get ready for another character purge before Christmas with the tram crash.
