What Does Belinda Blumenthal Realize About Dr Robbins While Helga Kisses Her?

At the end of The Dutchman's Leather Desk on My Dad Wrote a Porno, Helga kisses Belinda Blumenthal, and Belinda watches Dr Robbins from the corner of her eye. He starts shifting his weight from one foot to the other, the same trance-like sway he fell into earlier while staring at her.

Belinda suddenly understands what is going on. Dr Robbins is a voyeur. He wants a show, and she and Helga are the show. The hosts say they already knew he needed one. Helga, whom they have been mocking as a cut-price version of other women in the book, is about to perform for him. The realization ends chapter three.
