She attended David's memorial service.
I have never seen the pic, but many fans of the show have posted comments stating his nephew Jack posted a pic of him and her online. I am not surprised. Despite whatever rift occurred long ago, they were friends and costars once. Her attendance is the considerate thing to do. I wonder who Jack's dad is? Is he in the entertainment business ? I wonder if Danny , Jeremy, or Brian were able to attend? Or even Suzanne or Dave's family? It is possible Susan and David made peace before he passed. Then again , it' s their business.
