She's (always been) wise beyond her years.
Even in a terrifying lockdown, Abby found the time to put it all in perspective. While weighing their options with gunmen lurking outside, Abby told Janice about the time her fifth-grade class watched a crime movie where the bad guys wound up dead at the end. She said she'd never forget her teacher's speech on why it's not okay to applaud death—no matter how terrible the deceased person was. To this day, Abby carries that story with her as she works on even the most vile cases as a reminder that life is valuable.
