As someone already mentioned, there are too many problems in this one chapter. Gilbert gave up too soon when he was set up to be an overprotective grandpa for the entire story. Leold was pondering for too long. The wyvern should already been out of his sight by the time he chose to act. His lightning magic should hurt Shelia too. The wn version makes a lot more sense in comparison. So I don't know what the author was thinking when they wrote this inferior version.
