Quote Scotia: IF Didi dies as a result of a car driven by DUI Jack, then Sharon has her death on her shoulders, because Jack will have fallen off the wagon as a result of her switching the results of Summer' s paternity test.
Therefore, not only will she have destroyed Jack, but also Billy, Chloe and who knows what psychological damage to Summer, learning first Nick isn't her bio dad, then to find he is! Nick also IMO has to share some of the blame for keeping the original test results secret for all the years, and not having the test redone immediately after the original inconclusive result.
There has been a lot of fallout from this DNA mess, but the death of a child, if it happens, is a tragedy which can't be undone.
I agree Nick shares some of the blame. If Sharon or Jack is driving the car that kills Delia, the fallout will be HUGE! It will be huge no matter who is driving, but if it's Sharon or Jack it will really be huge.
