Adrian Jr. (spoilers)
So the carer told Tony that Veronica was Adrian Jr.'s sister and Sarah (Veronica's mother) was Adrian's mother. Well, the film implies Adrian Sr was the father but I can't help but wonder if Tony was the father. Tony being Adrian Jr.'s father is just about the only explanation I can think of which at lease somewhat explains why Veronica could still be so angry with Tony after all those years.
Any thoughts?
