A volcano erupted, startling the Doctor awake from their chaise longue. The Master stood over them in front of an altar where a large, multi-spired crystal shone. “Welcome -- welcome to your new Master!” he cried, reaching down for the Doctor. Before they could touch, however, the Master tilted back his head and ejected a diabolical laugh.
The Doctor gaped. The Master was practically on top of them. How could they escape? Then a bolt of lightning touched down, and the Master vanished. Smoke surrounded the Doctor as images of Minoan deities flashed about them. “Jo!” cried the Doctor, coughing on the smoke. “Jo!”
“Doctor, are you all right?” There was a touch on their arm, and the entire experience dissolved. They were slumped at a work table in UNIT HQ, and their assistant was peering at them.
Jerking upright, the Doctor straightened the ruffles at their neck. “Oh...I must have been dreaming.”
Jo produced a cup and saucer, contents steaming. “I’ll say you were. I’ve brought you some tea. Have you been working all night again?” She looked at the Doctor’s latest contraption which stood, half finished, on the table before them. “What is that anyway?”
The Doctor shook their head. “It doesn’t matter. My dream -- it’s far more important. It might make all the difference the next time he shows up.”
Since there was only one individual who seemed to show up regularly for the Doctor these days, Jo knew exactly who they were referring to. “The Master, right?”
“Yes, Jo. Do try to keep up.”
“Dreaming about the Master again?”
“Isn't that what I said? He was looming over me, and there was a tremendous explosion -- I could feel myself shaking -- and a huge burst of -- “
Jo chewed on the insides of her cheeks. “Were there any trains going into tunnels in your dream? Or rockets blasting off in slow motion? Maybe some cannons firing? Champagne popping?”
“My dear girl! Don’t be silly!” The Doctor looked up sharply from their tea. “It wasn’t a celebration. It was a...a...mind-blowing cataclysm!” They spread their hands out, mimicking the spray of debris.
The Doctor cocked their head. “Why are you looking at me like that?”
Jo shook her head, letting her hair fall into her face so that they couldn’t see her trying [and failing] to keep a neutral expression. “And you think I’m the exceedingly dim one. Don’t you have any idea what a dream like that means?”
“Of course I do!” The Doctor swept to their feet, cape flapping. “I have to be prepared -- the Master is coming!”
“Yes,” said Jo, watching the Doctor stride off. “Yes, I suppose he is.”
