Missy and The Doctor in “Dark Gallifrey: Missy - Part Two”

Do you have any idea about the consequences of your actions? Do you want to know about the war you started?

What war?

The Great Time War between Skaro and Gallifrey.

A conflict between the two does seem inevitable.

Oh, yes. Because you've already fought the opening skirmishes. You just don't realise it yet. Tell me -- what did you think would happen when you unleashed the Hand of Omega on Skaro's sun and incinerated their homeworld, hm?

I didn't pull the trigger...

Oh, no. You manipulated Davros into it. It was masterful. But do you really think that means your hands are clean, given you'd already been on a covert mission to avert the Daleks' very creation? Did you think he'd hesitate? That afterwards, they wouldn't retaliate?

Retaliation? It's a possibility.

It's a certainty. I survived it. I watched the universe burn, and all the dark deeds I've ever done pale into insignificance against its death toll.

Is that true?

Lord Voltaire's world was obliterated. The oceans vaporised. I once told him there were survivors, but I lied. He was the last of his kind and millions of other worlds suffered the same fate.

Something had to be done! I had to take a stand. The threat was only growing...

You lit the blue touchpaper on Armageddon and walked away. You see, we have so much in common. You'd burn worlds to get what you want, and so would I.
