Have Violet and Roscoe Been Chuck Cunninghammed?

[TMC]

In universe reason:

The daughter, Violet, moved away following her return from the failure of her life in Lake Tahoe. She got back together with Luke (the father of the child she gave up for adoption) and since she was on the program with her podcast blaming Christy (Anna Faris) her mother for her lot in life, the character has not been back on the series.

The son, Roscoe, grew older and in the fourth season went to live with his father. The actor is no longer with the program and is only mentioned in passing by his mother, which ironically isn’t seen on the program as being the serious dysfunction that it is.

Real life reason:

The series began to move away from the “Christy as a struggling mother” narrative in the fourth season. The Anna Faris/Allison Janney dynamic was preferred by viewers and the absence of children allowed for the series to become much darker than it would have been had they remained. Additionally, the interaction with and between women in their Alcoholics Anonymous group became the dominate narrative and that precluded the need to maintain the presence of Christy’s children.
