.................I hope you planned a sequel, too much left unresolved! As for Rover not going with Slade because Rover felt the need to settle the dispute with his raging maniac father ....whom last we saw was trying to kill him! I have no idea what is left to resolve there! Does Rover think he can waltz in to his home and settle things? One thing I noticed in the closing scene 'Each step he took was followed by the other faster, the thumps of shoe against metal lighter, his heart and body becoming more and more weightless until Rover was sure that he, too, was flying.' Did Rover inherit some of Slade's powers? If so, he may be on more of an even keel when confronting his father. Anyways, this certainly requires a sequel!
