After getting over his initial fear, Paul makes friends with the old ghost. Sir Simon seems to be an outsider, exactly like Paul.
Legend has it that Sir Simon killed his great love Flora, which doomed him to forever walk the halls of this eerie castle. Nobody seems to fear him, which disturbs Sir Simon a great deal. He is now pretty bummed out that the castle is going to be sold, and Paul wants to help his friend out of his blue mood any way he can.
