Faris’ Christy and Janney’s Bonnie went through a lot during those seven seasons, and working as the often dysfunctional mother / daughter duo probably helped the actresses form their own kind of bond.
So, it would be a bit of a shock to the system for Janney to now be faced with working without the woman who had been her frequent scene partner in crime.
I’m sure it’s nice for fans to hear that Allison Janney, and the rest of the cast and crew at Mom, are happy that Anna Faris is happy, and that Janney is able to express that while also admitting how “very odd” it’s been to do the show without her.
