David and Vivian have tentatively decided to reunite. Well, to attempt a reunion, anyway. However, there remains the problem of Vanish and Simone. What will happen to them? Vivian suggests adoption, but this suggestion makes David rather wary. Vanish, too, has his doubts, although he appears willing to try. In the meantime, Tre has summarily decided she would like to return home and Mel announces that his study of the magic book makes this a feasible option. Vanish then suggests that everyone should accompany Tre on her journey. Carl, naturally enough, dismisses this suggestion out of hand, but Irene persuades him to come along. And so, soon after, they arrive on Tre's world, none the worse for wear. But all is not well. As Tre acts as a tour guide by showing everyone the sights, an intriguing and fascinating inhabitant of her world sends a message to Simone about an imminent danger. It's then up to the visitors to prevent a momentous disaster from occurring. Thankfully, it is the unpredictable and bizarre powers of the diminutive Simone which ultimately save the day, by employing an amazing strategy.
