Owen is cynical, cutting. He always has to bite back; can never connect with another human being; afraid of being hurt again. No relationship has lasted longer than a month; he just can't bear to be around people who have something to lose because he knows that they will get hurt, that he will hurt them. So he cuts himself off from the world, no longer socialising in pubs or bars, preferring to spend time alone, thinking on the universe, in all the things no one else knows about. Jack knows, that although Owen had anger, deep down he cares.
