Re: 5x10 Vincent and the Doctor (Grading/Discussion) SPOILERS!!
Yes, I just rewatched those parts. At 23:38 or so you can see the blue item belted to his chair. Watch them walking down the road, around 22:16, you can clearly see he's wearing brown pants (might be pin stripes?). Why are you convinced they're pants? The belt you see was used to strap stuff to his chair. No idea what took him so long - maybe Amy's a faster runner?
