If Egon had a child in 1990 then the mom could have had a teen pregancy at 15 which would explain why the dad is out the picture. JasonNo way she's a granddaughter. Math doesn't work.She's a teenager meaning she was born in, we'll say 2005, for her to be granddaughter that would mean her parents would've had to be born in the 1980s. Egon didn't have kids so unless were playing a card that said he had a family or illegitimate children during the original movies.... She has to be daughter her fathered late in life. 30 years isn't enough time to span TWO generations.
