GL CLASSIC MOMENT #56

(We're not giving background on #55: Josh learns about Reva's cancer, since it aired within the past year).

A.C. Mallet was Harley Cooper's instructor at the Springfield Police Academy. They fought, they bantered, they fell in love -- though both were particularly loathe to express the sentiment out loud.

But then, while investigating a murder, Harley got locked in a root cellar by the killer during a snowstorm. It was quite cold. Mallet came to her rescue, but Harley developed hypothermia and, delirious, blurted out that she loved him. What man could resist?
