Mac2 deduced it would not be sensible for its activities to be subject to the continual monitoring and scrutiny of MI6 operatives. It encouraged Mark to take immediate action to disable the communication microchip in his body. Surgical removal was not an option as a) it would be dangerous and b) it would involve a third party. Disablement was the only possible option.
However, total disablement would cause MI6 to smell a rat. Switch on: switch off disablement would be perfect. This was something Mark set as his interim goal. It took him 9 full days.
Now for some fun!
