A victim gets one in "Brown Eyed Girl". Sophie, a 17-year-old girl who had aged out of the (literally) Axe Crazy predator's preferred age group, was about to be "replaced" by Mandy, a cop's daughter. Isles discovers that she had been a captive for four years, and still fought to the death to protect Mandy, a total stranger. The kid died a hero.
Jane still bears the scars from when Hoyt literally pinned her hands to the ground. She got her revenge later in the episode by putting a bullet into both of his hands at once, telling him, "We match."
A trio of girls get one for taking down a corrupt and pedophile teacher who'd driven one of their friends to attempt suicide. By each one claiming to be the driver of the car that ran him down and giving all but identical stories with the only change is each one is the one who first confronts the man, they are able to exploit Loophole Abuse to create reasonable doubt as Massachusettes law states only the driver can be charged with vehicular manslaughter, and get away with it.
Korsak gets one for taking on a mother-son duo of serial killers who have him shackled in his basement, bleeding from a blow to the head. Despite being incapacitated, injured, and knowing what these two have done previously, he never loses his cool, goading the male killer on being a Momma's Boy and even snarking at him while the young man angrily cuts into his throat with a scalpel. He manages to turn the pair against each other to the point where mother actually shoots son, and buys enough time for Jane to burst in and shoot the deranged mother. Then Korsak tells his friends to call for an ambulance, not for himself, but for his would-be killers.
Cavanaugh gets one when he tells off Rizzoli's Jerk AssAlcoholic Father after he openly insults Tommy, the one person who was willing to forgive and accept him for his parental failures.
