One thing I thought about from ATSD is that Vanessa may not exist in the 2nd dimension. Although it appears that most things are the same (marriage, early life, and age wise), Doof had a different childhood from Alt. Doof. Therefore, he may never have gotten married to (and later divorced) Charlene, meaning Vanessa does not exist.
