Dottore was much more secretive over things of higher importance to him. So while his colleagues and the mages were aware of his interest in the three moons, no one predicted his true goal. Your capture.
The second of the Fatui Harbingers relished in the look of shock and horror etched on the faces of your little hero squad as they watched him trap you just before he froze time, stopping all pursuit.
Dottore knew the Tsaritsa wouldn’t intervene. This didn’t concern her after all. And with the power of the three moons beneath his fingertips, no one could stop him. No one could take you away from him.
It wasn’t like you needed to be rescued. The Genius Scientist didn’t see you as just another experiment, an ant to be stepped on. He saw you as the only one worthy of being his eternal companion. And maybe he even loved you, in his own twisted ways.
“You might hurt yourself, sweetheart.”
Dottore clicked his tongue in disapproval. Though he couldn’t help the grin of satisfaction on his face. He’d been successful in attaining you after all. Even your futile protests wouldn’t be enough to soil his mood. He’d already drained your energy with one of his devices.
