QE members certainly do have sharp eyes. One of them pointed out the scene in A War of Nerves in which MK does the gear shifting for HW after she dislocated her shoulder, so I had to see for myself, and sure enough, there it was. Too bad the storyline called for Milner to be in a sling rather than Sam, as HW clearly could have used one.
According to HW, she and MK shared the driving duties again for S8.
Totally underestimate the MK fans. We watch his every move.
Which is probably why he stays off screen unless he’s acting in a role.
