Im so enchanted by how the Master is originally characterized. He's devious and power hungry and his whole gimmick is hypnotism and disguise and he's frankly a little stupid but when he isn't manipulating people or allying himself with destructive forces out of personal gain, it's always out of fear and it seems to be an expected outcome that he'll end up backed into a corner and lash out. It only takes two serials for us to learn that the master is SCARED of the doctor, tied up with complicated feelings of care and resentment. This isn't something new who lacks, per se, but their fear is always hidden under their veneer of a cackling maniac. it's very clear from Delgados performance that this pervasive fear is a feature, not a bug, and he is not just naturally reserved, careful, and meticulous because he's a machiavellian evil genius, its because he's paranoid.
