See, I didn't buy Roy and the doctor for one second. They were people from different universes. Neither would have contemplated going on a single date with the other. I 'got' Roy and Keeley the way they were written in previous series, but you couldn't really describe either of them as a character now because we don't really see them do anything apart from sniff around one another.
I actually thought this week's episode was better than most of them this series, though admittedly that's from a very low baseline. At least there was some attempt to characterise some of the women's team, though it will tell you how long it's been since we saw anything of Shannon that DH didn't recognise her when we saw her delivering food at the start.
