Amiya did not see the Doctor's betrayal, nor Theresa's final bout of sorrow.
The Black Crown finally lands neatly in Amiya's hands as Theresa takes down the final assassin in the room.
Theresa
It's alright, Amiya. Everything's fine...
Theresa
It's over.
Theresa does not look at the one frozen in place before her. She gently pats the back of the child in her arms and leaves a kiss on her puerile cheek.
Doctor
......
Doctor
Theresa. I can't throw away this opportunity I spent millions of lives and myriads of years to reach.
Doctor
I can't let you ruin the plan for Originium. I can't... let you turn this great land into a beautiful but fleeting dream.
Theresa
And that's why you put Amiya in harm's way.
Doctor
......
Doctor
...Seeing as the King of Sarkaz has already seen my memories, I believe there's no need for any further explanation.
Doctor
Do you hate me?
Theresa
You hurt Amiya. You're about to hurt Kal'tsit, and the fighters who trust you so deeply.
Theresa
Is this how you treat those lives?
Doctor
I'll do what I can to ensure their safety in the ensuing conflict. This is what Theresis swore to me as well.
Doctor
We only... need you to die.
Theresa
Doctor... did you present yourself before me out of guilt?
Doctor
Guilt... is too light of a word, compared to everything I've done.
Doctor
We made too many choices in a time that even Kal'tsit isn't familiar with.
Doctor
I just...
Theresa
When Amiya grows up, if she remembers me, if she asks about me, will you tell her the truth... of how I left her?
Doctor
No.
Doctor
I'll help them search for another way to live.
Theresa
You'll help them search for a final moment of peace before Originium destroys Terra?
Doctor
I'm sorry... That's the one thing that's set in stone.
Theresa
You know it's futile... and yet you still wish to cure Amiya's sickness.
Theresa
Even if her family and homeland will all turn into the same hunks of Originium in the not-too-distant future, along with anyone and anything you'll ever know...
Theresa
You still don't want the girl before your eyes to suffer.
Theresa
That's what you sincerely feel. Your purest thoughts. Your innate nature.
Doctor
......
Theresa
And actually... I'm glad, Doctor.
Theresa
I'm glad you're real and trueβthe one who Kal'tsit willingly trusts, and in turn trusts us.
Theresa
You... the creator of Originium... {@nickname}. You are the poison that ruins everything, but also the antidote to it all.
Doctor
...What?
Theresa strains to stand up, stretching her arms towards the Doctor, instilling in the latter an instinctive urge to retreat.
The Doctor tries to move, but fails. Sorrow far surpasses the collapsing rationality at this moment.
Theresa touches the face beneath the mask.
Theresa
You're crying, Doctor...
Theresa
Well, that's the kind of person you are. You know your own fragility, you know how much of a threat I pose to you even at a time like this... and yet... you still came here.
Theresa
So, I still... am willing to believe in you.
Theresa
To trust in who you really are.
Theresa
To trust in our {@nickname} who brings the rain, dew, and sun.
