She was NOT married to Joseph Rockwell!
Caitlin hadn't seen Joe Rockwell in almost twenty years. He was now a successful Seattle contractor, who happened to be renovating the office where Cait worked as a stockbroker. But one thing hadn't changed - Joe was still a terrible tease, telling everyone he and Cait were husband and wife! Oh, sure, they'd been "married" in a pretend ceremony when she was eight, but now Joe wants to make their 'marriage' real!
