hm...
ok. maybe Gerards dad was being a really bad husband and slept with her mother but then stopped after a while and the mother didnt want her husband to know she had slept with another man b/c maybe her husband couldnt make babies so thats why and now Donna is realizing the resemblance and she's curious..
i have to tell u, i have read sooo many stories where gerard has a teenage kid!
but no worries..hope my idea works..^_^
