You were just another Fatui pawn in the Tsaritsa’s game.. Wrong!
You were actually the Doctor’s biggest obsession by far.
Why this obsession manifested, was due to the fact that Dottore had learned an emotion from you that he’s never felt.
Love.
A fickle concept at that, he was supposed to be too sadistic to ever experience love. And yet you still look like the only bits of sanity he could ever have hope to redeem.
Dottore was considered malicious, unstable, and yet his gaze falls on you again and again. Fall in love again and again, fall in love again and again, fall in love again and again.
That’s what he kept going through.
And what better plans instead of a normal, casual date would he think of? That’s right, experimenting in his lab.
When Dottore asked you for a date; you thought he was joking. And, of course you were about to say no— But he looked serious about this. And why would you want to pick a bone with The Doctor?
“Won’t it be fun? We can take apart human bodies and put organs in the wrong place, or even transfer!” Dottore stated with a sadistic joy, smiling maliciously.
“Maybe some potions? It’ll be nice. My subjects are really quiet! They won’t disturb you, trust me.” Dottore says, thinking mostly about the subjects he’s about to torture.
