Go for it, Joeytrom! I actually did something like that for fun. I wrote a whole synopsis about what originally happened before Barnabas went back in time to prevent it. Of course, there was no Barnabas, no Julia, no Angelique. There wasn't even a Petofi (since there was no Barnabas to encourage Magda to find a cure for Quentin). The events unfolded rather quickly, culminating in the death of Quentin and Beth and the family covering it up; I won't provide any details so you can compose your own version. Do it! It's fun! If you do, let me know what you came up with we can compare.
