Vixen's eyes widened - she was suddenly oblivious to the future around her.
"Why mine?!" She yelped.
The Doctor reached inside his coat and pulled out a thin, silver object. He held it up to Vixen's forehead and pressed a button. A blue light began to glow at one of the ends, and Vixen watched curiously as he ran the object up and down her head. He stowed it away in his jacket pocket and looked away from her as he began to speak again.
"Your blood is mixed differently. That's why people find it so hard to act around you." The Doctor said.
Vixen couldn't even be bothered to ask how the Doctor knew about how people acted around her. She just nodded, as though she was pretending to understand something she didn't know. The Doctor suddenly turned around and walked them both back to the TARDIS. He opened the door for Vixen. She slowly, shakily, walked in and stopped when she got up to the dial board.
"How long will I have to wait for the monsters to leave?" Vixen asked the Doctor.
He ran up to her and began to press a few buttons on the dial board.
"As long as possible." He turned to face her and an awkward silence fell between them, "You could stay with me for... longer, you know." He said.
"What do you mean?" Vixen asked, her head on one side so her hair fell down gracefully.
"I sometimes have a... companion, who travels with me in time and space." The Doctor said rather hurriedly, "You could come with me for a bit, you know."
Vixen's face broke out into a wide smile. The rarest smile ever, and the Doctor looked kind of taken aback as Vixen answered.
"Why not, eh? I love a bit of adventure." She said, smiling.
The Doctor held out a hand, "Nice to have you aboard, Vixen."
"My pleasure." Vixen replied, and with another pull of a lever, the TARDIS had left the year 3057, and was going through the vortex of time that Vixen had so clearly seen in the Doctor's eyes.
