As Watson bellows Holmes’s name repeatedly over the falls, we see Holmes clinging to the hillside some distance away, watching his friend. At one moment it almost seems as though he is about to respond with a cry of ‘Watson’, but then he stops himself. Brett explained:
‘That was deliberate. It wasn’t in the script but I just wanted to show that Holmes had affections for Watson and for a fleeting second they almost get the better of his practical mind. But they don’t. [Large Brett grin.] It is a moment.’
“I had a strong sense as a kid, who was constantly belittled by vile PE teachers, that I would prove people wrong who said I spent all my time daydreaming. When I’d walk around the perimeter of the football pitch in the pissing rain and feel the terrible smack of the football against my cheek, I had an inner conviction that I could somehow make use of my geekiness. And I’m very pleased to say I have.”—Mark Gatiss (via jamismydrug)
When the Ninth Doctor first asked Rose to travel through time with him and refused, the Doctor accepted that and moved on. He traveled through space and time, saving the universe, all lonely for years thinking “I wish Rose could have been here.” Eventually, he goes back to a few seconds after he left Rose and says “By the way, did I mention it also travels in time?”
Rose never knew how long the Doctor waited for her.
