Cassidy was married to Brady for 18 years. Both lawyers, she worked pro-bono in the medical network, while Brady was a high profile corporate attorney and traveled a lot.
After years of tension, Brady left Cassidy to be with another woman on the other side of the country who gave him the kids she never could. Early in their marriage they tried multiple times, but unto multiple miscarriages. She felt Brady resented her ever since.
Recently Granpa O'Neil moved in with Cassidy under the guise he needed help, but really he couldn't stand her having to be all alone in the little apartment she moved into. Too hurt by recent events she remained unemployed and stayed at home reading. Granpa has a hope to set her up with someone new before he passes, but he really doesn't like any of the guys James and Sean are friends with.
