During "Blue Bloods" Season 3, viewers saw the departure of Danny Reagan's original partner, Jackie, and the introduction of his new partner, Maria Baez. While the season was generally well-received by audiences, Episode 7, "Nightmares," received the lowest rating on IMDb with a score of 7.6. This episode featured Danny searching for a killer in the Haitian community while Erin and Nicky took Danny and Linda's sons out trick or treating. Frank also dealt with a dark secret involving Garrett and an accusation of sexual assault. The low rating could be attributed to fans' dislike of Danny's new partner as well as concerns about how Frank handled the sexual assault accusation.
