Both Hermione Granger and Ron Weasley from the Harry Potter series are friends with Harry Potter, are scared of Lord Voldemort, are loyal friends, are friends of Hagrid's, are enemies of Draco Malfoy, don't like Professor Snape, are in the Gryffindor house, go to Hogwarts, have the same classes (in most of the books)... the list could go on.
