At Paul's wedding, Paul gives a speech saying that Connor was always there for him, "ever since our parents died when I was 2 and Connor was 7". However, in the scene showing when Connor and Jenny were just kids and she gives him a camera for his birthday, Jenny and Connor appear to be at least 10 years old - certainly not 7. Connor tells his ghost, "that was the summer before my parents died". The scene that follows shows the parents funeral, with Paul sitting next to Connor, and Paul appears to be about 5 or 6 years old - but much older than 2.
Christa B. Allen, who plays the teenaged Jenny, had previously portrayed another younger version of a Jennifer Garner character in 13 Going On 30.
