Oh, man, I'm so sorry I didn't reply to this sooner. This happens more often than I'd like, I'm afraid. XD

Thank you! I've always preferred my villains more subtle and psychological, too. Blowing up a city is fun and stuff, but when you get down to it, it doesn't take very long in the end. Using Owen allowed Gray to really relish every second and to take his sweet time. (Fun fact: He meant to kill Owen a lot sooner, but he got wrapped up in things and kept putting it off.)
