Did Mindfang actually rape Dolorosa? I knew that Mindfang mind controlled her to make Dualscar jealous, but someone told me that much more awful things took place, but I'm not sure if it's true

It’s not 100% confirmed that it was the Dolorosa. Mindfang definitely mind-controlled the slave to do sexy stuff to her, so at the very least its sexual assault, we don’t actually know how much she made the slave do so whether it was rape or not it debatable
