Brooke Gets Even with Bill Spencer

Bill's plan backfired when the Logan women banded together...

Brooke was horrified when Bill turned up at her home and told her that they could be together now.  He had lied when he said he was going back to Katie.  He only told Katie that to get her to return control of his company to him and give him equal custody of their son Will.

Katie arrived to here Brooke tear strips off Bill for his lying and manipulation of both her and Katie.  Katie lamented after Bill's departure that he now had everything he wanted.  But Brooke's sly little smile and "Or so he thinks" told viewers there was more to the story....

What did Brooke do?
