As a final idea on the Gillian actually lives list, there is always the dream sequence for Jake or some other poor sod ala Dallas where the last week didn't really happen. That could fix a lot of things. Maybe even the past few months? Tad and Dixie are still together with no David Hayward in sight. Laura is fine and didn't really even have a drug problem. Anna is alive, but goes to Port Charles instead of Pine Valley. Greenlee doesn't really work for Erica like a dog. JR is still Junior. The down side is that Hayley has the longest pregnancy is soap history.
