M (Judi Dench)’s Timeline and Summary

M orders Eve to take the shot that kills Bond.
Under scrutiny from the government, M refuses to admit any mistakes.
Bond returns to work, and M lies about his evaluations to get him back on the job.
At her hearing, M makes a strong stand about the necessity of her job and her department.
That necessity is proven when Silva attacks the hearing itself.
M is ushered away to Skyfall by Bond, where she will be used as bait to lure Silva.
M is shot by one of Silva's men, but she hides the injury.
After fleeing Skyfall through a secret tunnel, M is captured by Silva, anyway.
Bond kills Silva, but M succumbs to her wounds.
M looks at Bond, says, "I did get one thing right," and dies.
