Donald Mallard
- Donald Mallard: Oxytocin is often referred to as "the cuddle hormone." It is responsible for our feelings of affection. For someone in the midst of a suicide to experience, well, emotions that would cause that hormone to spike -- well, it's very odd.
- Donald Mallard: [realizing that Turner's suicide saved her daughter's life] Well, that would explain the spike in Turner's oxytocin level. Her suicide was not the act of a depressive individual.
- Leroy Jethro Gibbs: It was an act of love.
- Timothy McGee: A Sophie's choice.
