I love Grayson's "entrance" in episode 675 (on today's slideshow). The shots I'm thinking of aren't among the captures in the slides, but as I recall the episode, we see Julia's hand holding a cigarette, a shot of her coat, and then a close-up of the Doctor herself looking even more world-weary and "over it all" than usual. FABULOUS.
Grayson Hall is my religion--I admit it!
