There is a very nice presentation of the challenge of teaching the foal independence, how hard it is for her, but how much love it shows. Paul learns this when he has to let the Phantom go back to Asateague. He tells Misty to go, too, but Misty stays and runs after them. Her home is with them, now. This movie provides a good opportunity to talk about showing love by letting go. The brother and sister have a very good, supportive relationship. And their grandfather (Arthur O'Connell) is strict and proud but understanding, as shown by his reaction when Paul goes off to Asateague alone.
