"My expertise."

Dalia wanted to drag Walter out of this place. 

A place who she doesn't know why it's open in the afternoon but thanks to it she discovered that the person who helped Larissa was not leaving the best life.

She stared at Walter for a moment and said nothing.

It's uncomfortable for Walter but he just let Dalia stared until she had enough.

She then left without a word and Walter continue to his work.

He was not the only man present waiting for their customer, it's a club open in the afternoon for customers who doesn't want to be seen in the night purchasing such service.

Walter thought Dalia finally gives up and forget about her but a few hours later, while he is still on top of his other customer, a group of men wearing black suit came and fetched him, literally.

Well, wlater just let them take him.

He is still naked but he doesn't care.

It's pretty obvious for him that it was Dalia.
