Actually, I was just going to have Hudson get away. Gavin's got way too much of a happy-go-lucky attitude towards "adventuring", so this was to make him realize that there's actually a danger associated with it, and that exploring isn't just going around doing whatever you want with no repercussions. It's also because that gives him a good reason to join the guild. He's forced to find somewhere to stay in Treasure/Allure Town because it's so late in the day and he doesn't have enough supplies to get back.
