In Season 4, Episode 12, “Dial M for Mayor,” Penny Johnson Jerald revealed to the magazine that we’ll see the softer side of Gates when she explains some pertinent family history to Beckett.
“You understand more why she’s a police officer,” Jerald said.
During the same ep, the crime writer’s place at the precinct is put in jeopardy when his good pal Mayor Weldon becomes suspect numero uno in a murder case. “If the mayor’s ousted, it’s up to Gates to decide if Castle can stay,” Jerald says.
We can only hope her newfound sensitivity will spill over into her decision!
