Understanding how dangerous this Sutekh is, you realize that not only are you going to die, but all mankind as well. The only rational option is to hijack the TARDIS midflight, and flee into the depths of the TARDIS itself.
You willingly go in the TARDIS and once it dematerializes, you thrust forward and flip the little switchy thingys you know nothing about. To your great surprise a glare of light from the sun blinds you and you hear whistling in your ears. Then, too your horror you realize you are falling. You look down and realize you have materialized 50 miles over a planet and are falling to your death. You look to your left and see a potted plant falling as well. Petunias, you suspect. Beside it you see a very confused falling whale. It doesn’t do to mess with timey whimy things. You know nothing, John Doe.
In 3 minutes and 21 seconds you die. So does the whale.
