Why Is Belinda Blumenthal Upset at the Start of Belinda Blinked 2?

Belinda Blinked 2 opens with Belinda Blumenthal answering a pager. It is Tony, the managing director, telling her to get her ass into his office, pronto. She says yes, sir, and on the double, and she is already distinctly upset.

On My Dad Wrote a Porno, the hosts ask why. After everything she did for the company the day before, at the tennis party in the maze with Peter Rouse, she does not see why she should be treated like the office cat. She is still furious when she knocks on his door two minutes later and sits down as ordered. Tony slides her a fax.
