Anya tried to sneak into the audience section but the venue was tightly guarded. She didn't have time to disguise herself. Hence she went to the balcony to check around as she asked Senon, "Where is the model right now?"
The reason why Senon couldn't take the lead was, that a model was scared to death in the green room. The criminal had notified her to take his car right after the show. Failing to do so, he had threatened her with her nude pictures taken when she was changing during a show.
She was completely aware that she would never be able to get freedom becoming their s*x slave. But she couldn't go against him either as the criminal would leak her pictures and end her career, shame her family. She didn't have enough confidence to face him.
