It is Boys Vs Girls with the NYPD and the Attorney General's office with the CIA thrown in there. As the NYPD "welcomes" back Castle. As he and Ryan and Eposito investigate a former TV washed up actor's death.
But since Kate and partner Rachel come into the picture to take over the investigation due to national security and not telling them anymore hence the Need to Know title.
NYPD thinks that Kate has "betrayed" them as it gets very competitive as Castle is caught in the middle. As the so-called swing vote.
But the CIA comes in and boots both of the NYPD and Attorney General's Office off the case. As Kate does something that you would have to see as this involves her own job.
Rachel was a love-hate relationship. But still, she admired Kate's toughness and not seeing beyond black and white.
