THAT NIGHT EVERYONE SLEEPS IN THE TARDIS SO THE DOCTOR CAN KEEP AN EYE ON THEM.
"Uh Doctor?" Jack asked nervously, stuffing his hands into his pockets.
"Yes Jack?"
"Do you um want me to stay again tonight?"
"I'd be upset if you didn't"
-Later that night-
"You know it's not the silence right?" A familiar voice cooed beside The Doctor's head.
"Of course. I wasn't sure you'd ever come back." The Doctor said calmly.
"I see you and freak over here have developed a nice relationship"
The Doctor winced at the nickname. "Why are you here, Koschei?"
"I missed you, Theta."
A/N guess who's back? YOO (a few months/years??? Later?? When did I write this chapter? Like.. 2014? Ish?) when did they ever call each other theta and koschei like am I hallucinating or was this a canon thing?? I don't even remember anymore I haven't watched any season with 10 in AGES.
