Question: How old are Nick and Elizabeth? Hallie says that Nick's fiancee, Meredith, is young enough to be her sister. This would imply that Nick is at least sixteen years past Meredith's age, twenty-six. That would make him forty-two, so he was thirty or thirty-one at the time the girls were born. However, Meredith left Nick because they were "so young" and didn't get along. The early thirties years are not usually considered young ages for getting married and having children.
Question: When Chessy finds out Hallie is really Annie, she says she was 7lbs and 21inches long when she was born. That is NOT a small baby. Is it possible to have twins that big? I know twins usually come early and are very small.
Question: When Nick and Elizabeth are looking at Nick's wine collection, what does Nick mean when he says, "I think my sister was conceived on this"?
