Corrected entry: Jack the dog appears from nowhere early in the movie and is taken in by Alex. In the future, Kate, who has not yet met Alex, owns Jack and mentions her name in a letter sent to Alex. Since at that point in the film their paths had not crossed in either present or future, where did the dog's name come from? For that matter, where did the DOG come from?

Correction: I remember her saying " come on Jack, come on Jackie!" Jackie was said very quickly.
