Continuity: In the final scene with Andrew Beckett dying in hospital, he is wearing an oxygen mask. The LHS green strap is outside the mask when the mask is removed. When put back by Joe Miller it is on the inside of the mask - this would also impact on the flow of oxygen to the patient. The next time we see Beckett the green strap appears on the outside, but no one was near to move it. What is also strange is that Miller doesn't correct the position of the strap as it looks really odd.
