John's Pov:
I am very happy and excited that my plan got succeed finally...
Yes, after listening to the news that my friends get caught and they are under custody, I feel very happy...
It's my plan...
I helped them to go to Grindelwald because they should get caught by the cops...
And I bait my sister to them in my trap, I don't care if they fuck her in real...
One of my friends has a strong desire for my sister, so it's easy for me to implement my plan...
And finally, I am succeeded with my plan...
I am happy if my friends' succeed to rape my sister, my revenge will get satisfied if they failed, my plan will succeed that they caught to cops, either way, I am happy...
Yeah, actually they should be caught in Mark's hands when they are attacking in the resort...
That's the reason I asked them that I want to listen to her scream once...
So by listening to her scream, I guess Mark will come and caught them to cops...
