Why Anna Faris Didn’t Appear on Mom’s Series Finale – E! Online

Gemma went on to say she believes that Christy and Bonnie are still close, despite Christy having headed to Georgetown for law school. “I like to think that she also got into a happy and healthy relationship and that she is very much still a part of her mother’s life and her friends’ life,” the writer shared. “We didn’t see her in the finale, but she is still part of that group.”

In addition, TV Line quoted Gemma as saying, “We felt that it was important to honor [Faris’] decision to leave the show. The audience knows that Christy traveled a great distance over seven seasons and overcame so many obstacles in order to follow her dream of becoming a lawyer, and it felt like that story had been addressed in a satisfying way, so we didn’t revisit it for the finale.”

Instead, the finale centered on Bonnie attending the wedding of Jill (Jaime Pressly) and Andy (Will Sasso), not to mention her dealing with husband Adam (William Fichtner) getting diagnosed with cancer. 

There was a brief reference to Christy when Bonnie mentioned her daughter while speaking to a new member of her Alcoholics Anonymous group. “We’re both sober, and we love each other,” Bonnie said. “She moved, but my point is my point.”
