Varian threw the trash into ghostship and had Boo 'interrogate'.
Under his unintentional training, Boo was becoming more and more proficient in matters of kidnapping, torture, and interrogation.
Varian also had those three members of level 6 he kidnapped from earlier. After his training, Boo put them in a coma and did some brainwashing.
Apparently, he and Sarah were targets of assassination. It was a pity that they too had no information on the real mastermind.
'But seriously, isn't Boo enjoying this too much?' Varian tapped his chin and thought.
"P-Please! N-Not there. We'll reveal everything."
"I-I'll even reveal the secrets of my grandfather."
"Fuck you guys! I can reveal both of their secrets. Just promise that you'll kill me."
"Muahahaha!"
Varian listened to his little ghost's sadistic laughter and sighed in disappointment.
If only Boo was like him. He never tortured anyone. What a morally upright person.
