How Mom wrote off Anna Faris' character

Entertainment Weekly

"It was important to us that Christy moved on to bigger things," showrunner Gemma Baker tells EW of Faris' Christy. "Quite often when people are in recovery their lives get bigger in ways they couldn’t before have imagined. And so that will be the case for Christy. She has been working toward her dreams for a while now and we feel like the audience will be happy for her. The character of Christy will live on and we will continue to get updates on what she is up to and how her moving on will affect Bonnie."
