Darcy and Aiden, fourth graders who previously sought advice on confessing their feelings, return to share that Aiden has reciprocated their affection. The hosts also discuss whether lingering smells are real or psychological, featuring researcher Claire Dumar who explains that smell molecules are broken down by enzymes, making persistent odors a matter of memory rather than physical residue.
