It was warm summer day and Missy was enjoying a lovely cup of coffee outside a French cafe. After a long hard day of raising an army of Cybermen Missy needed a break. Behind her Missy noticed a figure dangling from the Eiffel Tower. She pulled a pair of binoculars from her handbag to get a closer look. That figure was in fact Missy's beloved boyfriend, though he didn't know it at the time. Then again to be fair at the neither did she. Missy hadn't seen the Doctor wear that face in such a very long time, she actually began to miss it a bit.
"oh dear, I don't think I should be here right now" Missy spoke to herself as she glanced at the vortex manipulator on her wrist. Missy punched in the activation code and was gone in a flash of light. When she arrived at her new location Missy was standing just a short distance from three strange men and a young woman. She almost recognised them but couldn't quite put her finger on it.
Is this...? No, it can't be. Even I know that would be impossible. Unless... No, this can't be but the buildings, the people, the...the Daleks? Missy thought to herself.
The next thing Missy knew a Dalek was being pushed past her. It was then she knew where she was. Missy had gone to Arcadia right in the middle of the Time War. When Missy followed the Dalek with her eyes she noticed the four figures walking in its direction. She heard a shattering noise. The four figures stepped into a portal of some sorts but it led to a time and place after the war and away from Gallifrey. Voices were heard from the other side...
"sorry about the Dalek"
"and the showing off"
At that moment Missy knew if she were to leave the war this was her chance. She followed a young dark haired woman and seemed to unnoticed. Allthough she didn't catch the full conversation Missy did overhear something about Zygons and some very familiar names. Kate Stewart. The Doctor. Osgood. Missy thought about those names over and over until it clicked. She was in the black archive in UNIT hq. Missy quietly peeked around the corner of a nearby shelf to get a better look at the people in the room. Missy noticed the tenth Doctor first and thought to herself, sexier than I remember. Then she noticed got a better look at the dark haired woman. Of course, how could not have noticed that was Clara. A few moments later Missy turned around and saw an elderly man sitting in a chair close by and Clara talking to him. She was saying something about his eyes or something like that. The conversation bored Missy to death so she went back to the negotiation between the humans and the Zygons.
Seeing the Time War again and three different versions of her beloved Doctor gave Missy a nasty idea. What if she were to get a few of her past lives together. If one Master could take over the world with an army of undead Cybermen think about what two could do. Or even three.
