Frank reported Fiona to Child Protective Services (CPS) as an act of vengeance and retaliation after he was kicked out by Fiona and the kids.
Frank's Motivation for Calling CPS
Frank Gallagher, known for his utter self-centeredness and lack of regard for others, viewed calling CPS as a strategic and malicious way to "get back at" Fiona and her siblings. His decision was a direct consequence of their actions—specifically, their choice to remove him from the family home. This act was purely driven by spite, aiming to inflict hardship upon his own children as a form of revenge for being ousted.
Immediate Consequences of Frank's Call
Shortly after Frank's call, a CPS worker arrived at the Gallagher house. The immediate and devastating outcome of his vindictive report was the forced removal of all the children from their home. They were subsequently placed into foster homes, illustrating the severe and damaging impact of Frank's selfish actions on his family.
