Brief description
Amy and Charles are in the field looking for escaped convicts with newly acquired thermal imaging gear (headsets), when Charles looks at Amy and tells her that if she and Jake are trying to get pregnant, they should do it now, because the headgear shows that she's ovulating.
Amy: "I love these thermal goggles."
Charles: "Amy, listen to me very carefully. If you and Jake are thinking of trying, you are ovulating like crazy right now."
Amy: "You take that helmet off before I knock it off."
Charles: "What? Your basal temperature is off the charts. This is a good thing."
