She was great! And Mark Sheppard is a great character actor who gets guest or recurring roles in everything -- he was Badger in Firefly, Canton in this latest season of Doctor Who, is Crowley on Supernatural, Sterling on Leverage, and often does guest spots on lots of other, mostly sci-fi shows. I am delighted every time I see him, and I think this will increase exponentially now I've discovered he's so awesome as a person.
