How will it end? Janney wishes Mom had more time for a bigger ramp-up to the finale, but at least the series will go out on its own terms. Bringing Faris back for a guest appearance would give a proper send-off for Christy, but that path might be too worn for a show that has continually shunned expectations. In the series finale, “My Kinda People and the Big To-Do,” Bonnie gains a new outlook on her sobriety after dealing with difficult news. Could that news have something to do with Christy?
