Hello, <br/>I would like to know what exactly does mean " draw on his dark side" in this sentence I have read on a book: <br/>it's about a young samurai: <br/><br/>' althought he feared for his son's willingness to draw on his dark side in order to achieve a final victory' <br/><br/><br/><br/>thank's, it's a very good thing this place for to learn and enjoy English. <br/>jc
