A/N: In my Korean version of this I had Clara address the Doctor in 'jondaetmal', basically formal language. This can't really be expressed in English as it has no distinguishing linguistic mechanism between formal and informal aside from maybe altering your vocabulary used in conversation. But I wanted to show that it's been so long since Clara's seen the Doctor (after the three hundred years she spends clinging to the TARDIS in the vortex) that the familiarity between them is quite gone. This song scarily sums up their relationship.
[Trouble Maker - Now/There Is No Tomorrow]
Just like before, you made me hesitate again.
The you who says nothing is just like yesterday.
Try saying it straightforwardly, try looking in my eyes
Before this night is over,
Before the starlight disappears.
Do you even remember me? I know I won't easily forget you.
Us together, inside this maze.
The only thing I can count on is you.
Close your eyes, hold me, because
We have no tomorrow.
Come to me now, talk to me
We don't have a tomorrow.
Don't hesitate
Before it's too late, now
Don't push me further and further away.
Us two, right here, right now
Before it disappears.
I couldn't even say anything, so I just waved.
Goodnight, my love.
But the words will never leave my mouth.
